There are seventy-six events, including 33 mainshocks of earthquake sequences and the sequences of moderate events. The epicenters of some of mainshocks with M s ≥5 are related to the exposed active faults, yet not for others. Irregular recurrence behavior with low periodicity exists in the time series of 33 mainshocks. Such a time series can be divided into three time intervals. The longest and shortest inter-occurrence time between two sequent events are, respectively, 18497 days (50.68 years) and 27 days (0.0074 years). The average inter-occurrence times (or the recurrence period) for the whole time interval, the first one, the second one, and the third one are, respectively, 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years). The values of coefficient of variation vary from 0.199 to 0.503, thus indicating low periodicity of earthquake occurrences. The largest and smallest numbers and percentages of mainshocks in a month appear, respectively, in November and in April. The seismic activities are lower in the summertime than in the wintertime.

Introduction The Yunlin-Chiayi-Tainan area (denoted as the YCN area below) is in the southwest part of Taiwan (see Fig. 1 ). Due to arc-continental collisions (e.g., Hsu 1971; Tsai et al. 1977; Wu 1978; Tsai 1986), Taiwan is specified with high seismic activities and the occurrences of numerous larger-sized earthquakes (see Hsu 1971; Wang et al. 1983; Wang 1988, 1998, 2024; Wang and Shin 1998) produced by strong and complex tectonics. Shyu et al. (2005) considered the YCN area to be under the ‘initial collision.’ From west to east, three main geological structures in the YCN area (Fig. 1 ) are: the Western Coastal Plain, the Western Foothills, and the Central Range (e.g., Ho, 1988; Shyu et al. 2005; Teng et al. 2005). The Central Geological Survey (GGS, now the Geological Survey and Mining Management Agency), Ministry of Economic Affairs and numerous researchers (e.g., Bonilla 1975, 1977; Hsu and Chang 1979; Lin et al. 2000; Teng et al. 2005; Peng et al. 2004; Shyu et al. 2005, 2016; Chen et al. 2006) have recognized several main earthquake faults in the YCN area. Figure 1 shows several first-class active faults: the Chukou fault (denoted as CKF), the Chiuchiungkeng fault (denoted as CCKF), the Meishan fault (denoted as MSF), the Muchiliao fault (denoted as MCLF), the Liuchia fault (denoted as LCF), the Kuohsaioli fault (denoted as KHLF), the Hsinhua fault (denoted as HHF), the Houchiali fault (denoted as HCLF), and the Tsochen fault (denoted as TCF). The Chukou fault seems to be linked with the Chelungpu fault along which the 1999 M s 7.7 Chi-Chi earthquake ruptured. In order to help seismologists and geologists to explore numerous seismological problems in the YCN area, it is necessary to compile a catalogue of large earthquakes, consisting of pre-1897 historical events and post-1897 instrumentally-recorded ones. In the Taiwan earthquakes can be seen in many catalogues with different magnitude scales by domestic authors (e.g., Hsu 1961, 1966, 1971, 1980, 1983b; Li 1983; Cheng and Yeh 1989; Wang and Kuo 1995; Cheng et al. 1999, 2002; Chen and Tsai 2008; CMB 2011; Wang 2024, 2025; CMA 2025). Recently, Wang and Chen (2026) compiled a catalogue of earthquakes in the Taichung-Chunghua-Nantou area. A large number of international catalogues also include Taiwan earthquakes (e.g., CMO 1952; Gutenberg and Richter 1954; Båth and Duda 1964; Duda 1965; Rothé 1969; Lee et al. 1976, 1978; Utsu 1979, 1982 Abe 1981; Abe and Kanamori 1980; Gu 1983; Abe and Noguchi 1983a,b; Theunissen et al. 2010; Aretz 2016). In the followings, we will compile a catalogue including historical and instrumentally- recorded larger-sized earthquake in the YCN area based on the above-mentioned catalogues. Of course, the spatial distribution of focal mechanisms of earthquakes is important for a complete catalogue. But, this study cannot be done here because of a lack of focal mechanisms of historical events and many pre-1960 instrumentally-recorded ones. From the catalogue, some basic studies will be done to explore the seismicity in the area. Such studies are the epicentral distribution, time series of earthquakes, and the variation in inter-occurrence time between two sequent events. Irregular recurrence behavior of time series of events is a significant issue (cf. Goes 1996). It is useful to evaluate the numbers of events in respective 12 months of a calendar year. Larger-sized earthquakes often generate seismic damage, including deaths, injuries, buildings collapsed, and buildings damaged. The studies on seismic damage are necessary not only for scientific interests but also for social needs. 2. Data 2.1 Historical Earthquakes Several parameters, including epicenter, focal depth, seismic (or earthquake) intensity, and size, are usually used to represent an earthquake. Before the installation of seismometers, the events are named the ‘historical earthquakes’ in this study. The seismic intensity has been long used to represent the size or strength of an earthquake, especially for a historical event (e.g., Davison 1921; Richter 1958; Hsu 1979). The seismic intensity is a measure of the degree of ground motions that local people can feel, or the degree of damage for houses, buildings, and civil structures under vibrations. In 1883, Giuseppe Mercalli (an Italian volcanologist) first formulated the intensity scale. Since then, several intensity scales have been developed to quantify earthquakes. The Japanese also constructed their intensity scale. Kawasumi (1943) first applied the seismic intensity to define intensity magnitude, M K , for quantifying earthquakes in Japan. Kawasumi (1951) also correlated M K to the local magnitude for Japanese earthquakes. The Central Metrological Observatory (CMO, now the Japan Meteorological Agency), Japan reported historical earthquakes in Japan and Taiwan (see CMO 1952) by using a magnitude scale of M = 4.85 + 0.5 M K to quantify an event. However, several authors (e.g., Wang and Miyamura 1990; Wang et al. 1990) did not consider this magnitude scale to be appropriate for Taiwan earthquakes. In 1897, the Japanese installed the first seismometer at Taipei (cf. Wang 1998). Hence, this year is an important one to separate Taiwan earthquakes into historical (pre-1897) events and instrumentally-recorded (post-1897) ones. For a historical earthquake in Taiwan, Hsu (1961) first used the empirical formulas (Gutenberg, 1945; Gutenberg and Richter 1942, 1956): r = 2.3( M GR -1.3) 3 -1.7 or M GR =[( r + 1.7)/2.3] 1/3 to quantify Taiwan earthquakes. In the empirical formulas, M GR is Gutenberg’s (1945) surface-wave magnitude and r is the radius (in km) of the felt area to be considered as a circle. From the rules we have M GR >6.4 as r > 300 km; M GR =5.4−6.7 as 200 km < r <300 km; M GR =4.8−5.7 as 100 km < r <200 km; M GR <4.8 as r < 100 km. Although this magnitude scale (denoted as M H ) is also one kind of intensity magnitude for Taiwan’s historical earthquakes, it is similar to M GR . In order to estimate the magnitude values of some historical events, Tsai (1985) compared the spatial distribution of damage produced by a historical event with that generated by a post-1900 event whose location was near the historical one. When the two spatial distributions are similar, the magnitude of the post-1900 event was taken by him to be that of the historical one. Tsai’s magnitude scale is denoted as M T . Of course, there are some problems with the method. Due to the differences on the numbers of buildings, building structures, landslides etc. between the pre-1900 era and the post-1900 era, his method to estimate the magnitude of a historical event is questionable. Hsu (1961, 1966, 1971) first reported numerous historical earthquakes. Hsu (1980) compiled larger-sized historical events from 1644 to 1896. A catalogue of Taiwan earthquakes (including the occurrence dates, possible occurrence localities or areas, and damage of events) during 1682−1895 was compiled by Hsu (1983a) from historical documents. According to this catalogue and related information, Hsu (1983b) and Tsai (1985) anlyzed historical earthquakes and their damage. Hsu (1983) analyzed 27 historical events with magnitude values of M H =5.0–7.0 from 1644 to 1882. Tsai (1985) reported 11 historical disastrous events with magnitude values of M T =6.0–7.7 from 1683 to 1895. Cheng and Yeh (1989) compiled a catalogue of historical events during 1604−1897. Cheng et al. (2002) compiled a catalogue of disastrous earthquakes during 1736−1897. In addition, some historical earthquakes were also reported in Chinese catalogues (e.g., Gu 1983; Lee et al. 1976). The magnitude scales are denoted as M C for Gu (1983) and M Lee for Lee et al. (1976). The magnitude values listed in these catalogues were also estimated from the damage patterns. The values of related magnitude scales are listed in Table 1 . The magnitude value used to evaluate the value of M s is underlined. Table 1 The Yenlin-Chiayi-Tainan earthquake data (date, epicentral location, focal depth, H , and magnitude scales (as described in the text), e.g., M H , M T . M J , M U , M C , M Lee , M GR . M Abe , M Du , M Ro , M s , and M w . The value, which is underlined, of one of the magnitude scales is used to evaluate that of M s for pre-1967 earthquakes based on a related conversion formulae as described in the text. The value of M w is calculated from that of M s based on the equation: M w =0.71 M s +1.78. The values of M s and M w for post-1967 earthquakes are taken directly from the USGS’s catalogue.

Wang 1989, 1998, 2024). For instrumentally-recorded earthquakes, an important parameter to quantify the size of an event is the ‘magnitude’ which is measured from the amplitudes of seismograms. The local magnitude, M L . which was defined by Richter (1935) has been used to quantify an earthquake from local seismograms. Since Gutenberg (1945) proposed surface-wave magnitude, M GR , this magnitude scale was very important for quantifying earthquakes before 1963. In the early 1960's, the World-Wide Standard Seismographic Network (WWSSN) was constructed by the United States Coast and Geodetic Survey (USG&GS), USA for monitoring the global earthquakes. From the seismograms recorded by the WWSSN, the surface-wave magnitude, M s , is evaluated by using the "Prague-Moscow formula" (Venek et al. 1962): M s =log( A / T ) + 1.66log Δ + 3.3 where A is the maximum trace surface-wave amplitudes, T is the period (= 20 ± 2 sec) of the peak amplitude, and Δ is the epicentral distance in degrees. Since 1966, this formula has been accepted by the International Association of Seismology and Physics of Earth's Interior (IASPEI) to quantify earthquakes. Numerous international governmental agencies routinely determine the magnitudes of global earthquakes, including Taiwan’s larger-sized ones. Of course, numerous researchers compiled the earthquakes. Those agencies and researchers used different magnitude scales to quantify earthquakes. The CMO (now the JMA) determined the magnitudes of earthquakes in Japan and Taiwan by using the formula (Tsuboi 1951): M J =log A + l.731log Δ -0.83. In this formula, A (in µm) is either the larger value of the maximum amplitudes of seismograms along two horizontal components or the composite one of the two maximum amplitudes and Δ is the epicentral distance (in km). CMO’s catalogue includes the earthquakes of the YCN area from 1902 to 1927. Utsu (1979, 1982) compiled a catalogue to include numerous Taiwan earthquakes. The magnitude values of Utsu’s catalogue for the events from 1885 to 1950 were taken from CMO (1952). He evaluated the magnitude values of events from 1951 to 1980 by using the amplitudes measured from the seismograms recorded by the JMA’s Wiechert seismographs based on Tsuboi’s formulae. Utsu’s magnitude scale is denoted by M U in this study. Essentially, M U is equivalent to M J . Utsu’s catalogue includes the earthquakes of the YCN area from 1904 to 1964. Hsu (1961) first reported disastrous events from 1900 to 1960. Hsu (1971, 1980, 1985) quantified Taiwan earthquakes during 1934−1980 from the data observed by the Taiwan Weather Bureau (TWB) and the Central Weather Bureau (CWB, now the Central Weather Administration, CWA) based on Hsu’s formula: M H =log A + l.09log Δ + 0.50. From the formulas in use, M H is different from M J (cf. Wang and Miyamura, 1990; Wang, 1992). Although the definitions of Hsu’s magnitude scale for historical earthquakes and instrumentally-recorded ones are different, they are both denoted by M H here for convenience purposes. Hsu (1971, 1980, 1985) did not quantified the instrumentally-recorded events during 1897−1933. This is due to two reasons: (1) the number of seismic stations was very small before 1934; and (2) the quality of pre-1934 seismograms was not good and some seismograms were disturbed or lost during the Second World War. Hence, He could only take the magnitude values from other catalogues. Taiwan earthquakes were quantified in numerous domestic catalogues with different magnitude scales. Hsu (1971) published the first catalogue consisting of M H ≥4 earthquakes during 1936–1967. Hsu (1980) renewed the catalogue by correcting the events during 1936–1979 and adding several instrumentally-recorded ones during 1900–1936. Li (1983) compiled a catalogue of earthquakes with magnitudes ≥ 5. Cheng and Yeh (1989) compiled a catalogue of instrumentally-recorded M L ≥4 events ( M L =local magnitude) during 1898–1988. from Hsu's catalogue and the catalogue published by the Institute of Earth Sciences (IES), Academia Sinica. They conversed several magnitude scales into the local magnitude. Several authors (e.g., Gutenberg and Richter 1954; Båth and Duda 1964; Duda 1965; Rothé 1969; Lee et al. 1978; Abe and Kanamori 1980; Abe and Noguchi 1983a,b; Abe 1981, 1988; Gu 1983; Li 1983; Aretz 2016) reported the magnitudes of Taiwan earthquakes. Hence, the magnitude values used by some of these authors are used in this study. The magnitude scales in use are M GR for Gutenberg and Richter (1954), M Du for Båth and Duda (1964) and Duda (1965), M Ro for Rothé (1969), M Abe for Abe and his co-authors, M C for Gu (1983), and M U for Utsu (1979, 1982). Lee et al. (1978) compiled their catalogue by taking the data from 15 catalogues with different magnitude scales. Hence, the magnitude scale of their catalogue is quite complicated and thus simply denoted as M Lee in this study. Since Gu’s (1983) catalogue was not cited by Lee et al. (1978), the magnitude values of Gu’s catalogue are also used this study. The time periods of reporting the earthquakes of the YCN area are from 1927 to 1941 for Gutenberg-Richter’s catalogue, from 1904 to 1941 for Abe and co-authors’ catalogue, from 1661 to 1964 for Gu’s catalogue, from 1904 to 1964 for Lee et al.’s catalogue, from 1906 to 1941 for Duda’s catalogue, and only the year 1964 for Rothé’s catalogue. Some other authors (e.g., Engdahl et al. 1998; Engdahl and Villaseňor 2002; Theunissen et al. 2010) relocated or revised the locations of some Taiwan earthquakes from different sources. Wang (2024) took the results of the above-mentioned authors to replace the original ones listed in Wang and Kuo (1995) and then recompiled a complete catalogue for M s ≥7 Taiwan earthquakes during 1900–2024, including five more M s ≥7 events which occurred during 1996–2024. In this study, we must unify the magnitude scales used in different catalogues to M s . For pre-1934 instrumentally-recorded events, M s is evaluated M J through the relationship: M J =(0.25 ± 0.34)+(0.96 ± 0.05) M s (Wang 1992). For historical and instrumentally-recorded ones during 1934−1967, M s is evaluated from M H through the relationship: M s =(-0.95 ± 0.31) +(1.15 ± 0.05) M H (Wang 1992). For the post-1967 events, M s is taken directly from the Earthquake Determination Report (EDR), USGS. After 1999, M w may be directly taken from the EDR. The value of M s of the January 21, 2025 Dapu earthquake was calculated from its value of M w . The values of related magnitude scales are listed in Table 1 . The magnitude value used to evaluate the value of M s is underlined. From July to November, 1945, the seismic observational system in Taiwan was shut down due to the 2nd world war, seismic data were absent. This made the October 21, 1945 M C 6.25 Chiayi earthquake be absent in all Taiwan’s and Japanese catalogues (e.g., CMO 1952; Hsu 1971; Utsu 1979, 1982; Li 1983; Cheng and Yeh 1989; Cheng et al. 2002; CWA 2025). Nevertheless, this earthquake was reported in Chinese catalogues (e.g., Lee et al. 1978; Gu 1983). Hence, its magnitude value was just taken from the two catalogues. The seismic moment magnitude, M w , was proposed by Hanks and Kanamori (1979) to quantify an earthquake. At present, M w is the main magnitude scale for quantifying earthquakes by the USGS. The value of M w is calculated from that of M s for pre-1979 Taiwan events to which M w was not assigned from the expression: M w =0.71 M s +1.78 (Chen et al. 2007). For the January 21, 2025 Dapu earthquake, the value of M w was taken from the USGS and thus M s was calculated from M w . The epicenters and focal depths (denoted by H ) of earthquakes in this study were mainly taken from the CWA (2026). For some events which are not reported by the CMA, we got their related data either from the CMO (1952) for those with M J or from Hsu (1971, 1980, 1985) for those with M H . The epicenter of the October 21, 1945 M C 6.25 Chiayi earthquake was taken from Gu (1983). For several pre-1940 events, their focal depths are still unknown. The crust-upper mantle boundary with v p =7.5 km/s underneath Taiwan ranges from 35 km to 45 km with an average of 40 km (e.g., Rau and Wu 1995; Ma et al. 1996; Kim et al. 2005; Wu et al. 2007; Kuo-Chen et al. 2012). Here, the depth of 40 km is assumed as a boundary to classify the events: a crustal one with H ≤ 40 km and an upper-mantle one with H > 40 km. Most events occurring in the YCN area are crustal events. This is consistent with the depth distribution of shallow events in Taiwan (Wang et al. 1994). Seismic damage in Taiwan was documented with Chinese, or Japanese, or English. The CWA (2025) compiled a somewhat complete data set of seismic damage caused by pre-2023 earthquakes from different data sources. The data set is stored on the CWA’s website: https://scweb.cwa.gov.tw/zh-tw/page/disaster . Seismic damage of the January 21, 2025 Dapu earthquake was taken from Wu et al. (2025). 3. Compilation of an earthquake catalogue Seventy-six earthquakes, including 36 historical events and earthquake sequences and 40 instrumentally-recorded ones, which occurred in the YCN area from 1644 to 2025, were compiled from the above-mentioned catalogues. Table 1 shows the occurrence times represented by the local time in Taiwan, epicenteral locations, focal depths, and the values of magnitude scales. The focal depth was reported for historical earthquakes. There are high uncertainties of estimated epicenters for historical events. For instrumentally-recorded earthquakes, the pre-1967 events had larger uncertainties of epicenters and focal depths than the post-1967 ones. In Table 1 , we can see that there are abnormally large values of M J =8.5 listed in CMO (1952) for two earthquakes, i.e., the March 17, 1906 Meishan earthquake (cf. Omori 1907, 1909) and the January 18, 1964 Baihe earthquake (cf. Hsu and Lu 1969). The two earthquakes occurred in the time period when the Japanese occupied Taiwan and installed several seismometers in Taiwan. The magnitudes reported by other catalogues are not so large. The reason to cause such large values is unknown. Table 1 shows several particular earthquake sequences. One is the March 17, 1906 Meishan earthquake which were followed by numerous aftershocks. The other is the April 14, 1906 Yanshui earthquake sequence which sees a swarm. The August 25, 1927 M s 6.8 Xinying earthquake and the December 22, 1906 M s 6.8 Xinying earthquake seem to be the two largest events of ‘doublets,’ because their localities were close and the magnitudes were equal. Unlike the 26 December 2006 Pingtung offshore earthquake doublets whose time difference was only 8 minutes, the time difference between the two Xinying earthquakes was longer than 3 years and 4 months. Of course, the two Xinying earthquake sequences can be considered as two independent sequences. The former might influenced the latter. The earthquakes (mainshocks) with M s ≥5 which occurred in the YCN area from 1644 to 2025 are listed in Table 1 . There are four questions. The first question is: Was the magnitude of the March 17, 1906 Meishan earthquake (Omori 1907, 1909) larger than 7? Wang (2024, 202) deeply discussed this problem based on the values of different magnitude scales used by numerous authors. The answer is M s =6.8 < 7.0 for this event. From field geological surveys, Peng et al. (2004) reported that the Meishan fault is a strike-slip fault with a length of 25 km. From the relationship for strike-slip faults (Wells and Coppersmith 1994): log( L s )= (-3.55±0.37)+(0.74±0.05) M s , where L s is the surface rupture length, M s is 6.7 as L s =25.0 km. This value is similar to M s =6.8 as mentioned above. Hence, the magnitude of the event should be M s =6.8. The conversion equation: M s =(-0.95±0.31)+(1.15±0.05) M H (Hsu 1983b) leads to M H =6.74 which is smaller than M H =7.1 as listed in Hsu (1971). The second question is: Was the magnitude of the the January 18, 1964 Baihe earthquake, which was named the Tainan-Chiayi large earthquake by Hsu and Lu (1969), smaller than 7, because its magnitude evaluated by Hsu (1971) was M H =6.3? In fact, its magnitude values determined by other authors were equal to or larger than 6.9 as listed in Table 1 . Its value of M s evaluated from M U =6.9 is 7.0. Hence, we assume M s =7.0 for this event. There were two earthquake sequences in 1906. The third question is: Could the first sequence trigger the second one? The first sequence initiated from the March 17 M s 6.8 Meishan earthquake (No. 20) and then numerous M s ≥6 aftershocks happened. The second sequence stared from the April 14 M s 6.7 Yanshuei earthquake (No. 21) and then a larger-sized aftershock happened. It seems that the March 17 M s 6.8 Meishan earthquake triggered its aftershochs and the Yanshuei earthquake through stress transfer. In 1951, a similar situation occurred in the Haulien-Taitung area. The earthquake sequence started on 21October 1951 with the M L 7.3 Hualien mainshock which triggered numerous M s ≥6 aftershocks. Thirty-four days later, the M s 6.0 Chihshang earthquake was triggered about 100 km away from the Hualien mainshock. Three minutes later, the M L 7.3 Yuli earthquake happened about 5 km away from the Chihshang event. Two days later, the M L 6.0 Taitung earthquake appeared about 40 km away. Chen et al. (2008) deeply interpreted the occurrences of the earthquake sequence by using stress transfer. The forth question is: Whether or not the value of M s of the March 20, 1902 earthquake (No. 17), which happened to the west of the harbor of the Tainan City, is M s =7.5? This question is due to a fact that this large event did not cause seismic damage in Tainan which was a big city in 1902. There could be two reasons to explain why such a large earthquake did not cause damage. The first reason is that like two 1906 earthquakes as mentioned above, the magnitude value of 1902 event published by CMO could be over-estimated. The second reason is that the location of the earthquake determined by the CMO might be incorrect, and it could be somewhat far away from the Tainan harbor and located at the Taiwan Strait. This would decrease the possibility of producing damage. A significant example to explain this problem is the September 16, 1994 Ms7.3 earthquake which occurred at the Taiwan Strait offshore Tainan (cf. Chen et al. 1996). This event did not produce seismic damage in southwest Taiwan. The two reasons might be due to incomplete data for determining the magnitude value and location in 1902 when the seismic stations were very few and almost located in northern Taiwan. 4. Some results and discussion To consider the scope and length of this study, we will only focus on the mainshocks of the YCN area in the following studies. The mainshock is assigned the event number in Table 1 . 4.1 Epicentral distribution of the mainshocks The epicenters of 33 mainshocks are plotted in Fig. 1 with different symbols depending on their magnitudes. The larger the event is, the bigger the circle is. The first-class active faults recognized by the CGS in the area are also shown in the figure. Since the magnitude values and localities of nine historical earthquakes (including the mainshocks of earthquake sequences) have not yet estimated, they are not plotted in Fig. 1 . Figure 1 shows the localities of mainshocks, including 16 historical events and 17 instrumentally-recorded ones. Some of them have a high correlation with the exposed active faults. Nos. 12 and 20 were near the Meishan fault (MF). No. 28 was near the Tachienshan fault (TCSF). No. 07 was to the south of the Chukou fault (CKF). Nos. 08 and 25 were to the Muchiliao fault (MCLF). No. 24 was close to the Liuchia fault (LCF). No. 27 was on the Hsinhua fault (HHF). No. 09 was to the east of and near the Houchiali fault (HCLF). Of course, we cannot find the relation between the exposed active faults with other mainshocks. The sediments are generally thick in the area from geological surveys (cf. Ho 1988; Teng et al. 2005) and from the 3D seismic tomography (e.g., Rau and Wu 1995; Ma et al. 1996; Kim et al. 2005; Wu et al. 2007; Kuo-Chen et al. 2012). The related active faults might be below the sediments and thus hidden. In order to completely settle the question, more geological and seismological studies should be done in future. Figure 1 also shows several important and significant points. The August 9, 1792 M s 7.2 Chiayi earthquake (No. 12) could rupture and the March 18, 1906 M s 6.8 Meishan earthquake (No. 20) ruptured along the Meishan fault (MF). The time difference between the two events is ∼114 years. Since up to date there has been 120 years from the occurrence of the 1906 Meishan earthquake, this time difference is longer than 114 years. Hence, we should much pay attention to the possibility of the occurrence of the next Meishan earthquake in the near future. The August 9, 1792 M s 6.1 Zhongpu earthquake (No. 12) could rupture and the December 17, 1941 M s 7.2 Zhongpu earthquake (No. 25) ruptured the Muchiliao fault (MCLF). The time difference between the two events is ∼149 years. Since there is only 84 years after the 1941 Zhongpu earthquake happened, the occurrence of the next one could be not so urgent. The January 21, 1654 M s 5.6 earthquake and the February 15, 1661 M s 6.0 earthquake occurred to the east of Tainan harbor. No exposed active fault related to the two events has been delineated. There has been 1864 years since the occurrences of the two events. The March 20, 1902 M s 7.5 earthquake happened to the west of the Tainan harbor. It has been 123 years since such a large earthquake occurred. The magnitude value of the 1902 earthquake could be over-estimated as mentioned above. Nevertheless, we should still watch the possibility of the occurrence of a larger-sized earthquake on and near the Tainan City in the near future. 4.2 Time series of the mainshocks The time series of 33 mainshocks and the largest events of earthquake sequences are displayed in Fig. 2 : the dotted lines for historical earthquakes and the solid lines for instrumentally-recorded events. There are several groups of earthquakes with short inter-occurrence times. Since the lines related to them are much closer to one another, they cannot be separated very well and thus the lines become wider. On the other hand, the lines for events with long inter-occurrence times separate very much. In addition, the degree of clustering remarkably seems to be lower for historical earthquakes than for instrumentally- recorded ones. The number (= 16) of historical earthquakes that occurred from 1644 to 1895 (i.e., a longer time period of 252 years) is smaller than that (= 17) of instrumentally-recorded events from 1902 to 2025 (i.e., a shorter time period of 124 years). Figure 2 displays an increase in seismic activity of larger events from the first time period to the second one. This increase is important for prediction and forecasting of earthquakes in the area. However, the reasons to produce such an increase are not yet known. In order to mitigate seismic hazards, Taiwan’s seismologists and geologists should pay attention to this problem. Figure 2 obviously demonstrates irregular recurrence behavior with weak periodicity for earthquakes in the YCN area. This is an important problem for long-term seismicity of the area. This problem will be further discussed below. 4.3 Distribution of inter-occurrence time between two sequent events for the mainshocks The inter-occurrence time between two sequent events versus the first event number is displayed in Fig. 3 . The longest and shortest inter-occurrence times between two sequent events are, respectively, 18497 days (50.68 years) and is 27 days (0.0074 years). Three time intervals can be delineated from the time series: the first one from No. 1 in 1644 to No. 8 in 1720, the second one from No. 9 in 1721 to No. 20 in 1906, and the third one from No. 21 in 1906 to No. 33 in 2025. The average inter-occurrence times (denoted as µ ), which can be considered as the average recurrence period or repeat time. The values for the whole time interval, the first, second, and the third time intervals are, respectively, 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years). The average value for the whole time interval is displayed by a thin solid horizontal line and those for the three respective time intervals shown by three thin dotted horizontal lines in Fig. 3 . The values of µ increased from the first time interval (1964−1720) to the second one (1720−1906), and then decreased from the second one to the third one (1906− 2025). The average inter-occurrence time for the whole time interval is longer than those for the first and third time intervals and shorter than that for the second time interval. The average inter-occurrence times increased from the first time interval to the second one, and then decreased from the second one to the third one. This provides indirect evidence of irregular recurrence behavior of earthquakes in the YCN area. The mechanisms to result in this phenomenon are not yet known It is necessary to make more studies on the mechanisms. Such irregular recurrence behavior could decrease the possibility of long-term prediction or forecasting of M s ≥5 earthquakes in the YCN area. In order to statistically investigate the temporal variation in earthquakes, we may consider a method of calculating the coefficient of variation ( CV ) (cf. Forkman 2009). This coefficient is CV = σ / µ where σ is the standard deviation and µ is the mean for a sample of data. This value expresses the extent of variability related to the mean of the population. A distribution of data has normal-variance as CV = 1 or σ = µ . A distribution of data is completely periodic as CV = 0 or σ = 0. A distribution of data has considered to be low-variance or low-periodicity as CV 1 (e.g., Goes 1996; Satake 2015). For a time series of earthquakes, the meaning of CV is: CV = 0 for the periodicity, CV 1 for the aperiodicity. An increase in CV from 0 to 1 leads to a decrease in degree of periodicity. For the whole time interval, the first one, the second one, and the third one, the values of CV are, respectively, 0.199, 0.347, 0.287, and 0.503 because of the respective values of σ , i.e., 862.52 days, 1208.62 days, 1618.99 days, and 1618.41 days as based on the above-mentioned values of µ . Results indicate that degree of periodicity is the highest in the whole time interval. The CV value is the largest for the third time interval (1906−2025), the middle for the first time interval (1644−1720), and the smallest for the second one (1720−1906). In other words, the degree of periodicity increases from the first time interval to the second one, and then decreases from the second one to the third one. Hence, since 1906 the periodicity of earthquake occurrences has been the lowest and the degree of irregular recurrence behavior the highest in the YCN area. Figure 3 reveals direct evidence of irregular recurrence behavior with low periodicity of the time series of earthquakes. 4.4 Distribution of events in twelve months The numbers and percentages of events in 12 months of a calendar year are listed in Table 2 . Results are given below: For 16 historical earthquakes, the activities were relatively high in January and October, and low in May, September, and December. For 17 instrumentally-recorded earthquakes, the activity was relatively high in March and December and low in February, June, July, and September. The months with high seismic activities of mainshocks changed from historical earthquakes to instrumentally-recorded ones. For 33 mainshocks, the highest activity and lowest one appeared in October and in September, respectively. Seismic activities of mainshocks in the YCN area were higher in the wintertime than in the summertime. Table 2 The numbers and percentage of events in the calendar months for historical events (HE) and instrumentally-recorded events (IRE).

There are differences on seismic damage caused by different earthquakes due to different magnitudes, localities etc. Several earthquakes, for examples, the August 9, 1792 M s 7.2 Chiayi (Zhongpu) earthquake, the June 17, 1862 Tainan earthquakes, the December 3, 1906 Meishan earthquake, the December 17, 1792 M s 7.2 Zhongpu earthquake, the 1964 Baihe earthquake, caused serious damage in the YCN area. We must watch the possible occurrence of such kinds of events in near future and strengthen the quality of buildings and civil structures to mitigate hazards.

The first type is the social factor. This includes two components: First, the numbers of population, houses, buildings, and civil structures were much larger after 1900 than before 1900. Secondly, the emergency response (or resiliency) was weaker before 1900 than after 1900. The second type is the engineering factor, including two components. The first component is the quality (i.e., structural vulnerability or fragility) of houses, buildings, and civil structures, which was much higher after 1900 than before 1900. The second component is the extent and density of built environment (i.e., exposure). The exposure should change very much from the ancient time to the recent one. The two type of factors could yield higher seismic damage before 1900 than after 1900. The third type is the geological-seismological factor. Although this factor is originally controlled by the ‘nature,’ the previous two factors can also influence it. The human beings have harmed the Earth very much. This factor includes several components as mentioned below. First, the geological conditions are important on yielding seismic damage. Geological surveys show that the Western Coastal Plain and the Western Foothills are, respectively, to the west and to the east of the YCN area (cf. Ho 1988; Teng et al. 2005). The Tachienshan fault (TCSF) and the Chukou fault (CKF) are almost along the western boundary of the Western Foothills. The sedimentary layers are much thicker underneath the Western Coastal Plain than below the Western Foothills in the YCN area. This would strongly affect the spatial distribution of seismic damage. Secondly, large earthquakes could produce remarkable deformations and ground surface ruptures and fissures which can directly and indirectly result in seismic damage. For example, the 1964 Baihe earthquake caused many deformations and ground surface ruptures and fissures (cf. Hsu and Lu 1969) which caused seismic damage. The 2025 M s 6.4 Dapu earthquake produced co-seismic deformations (e.g., Lee et al. 2025; Lu et al. 2025; Sharma et al. 2025). Thirdly, large earthquakes, especially the shallow ones, for example, the 1999 M s 7.7 Chi-Chi earthquake (e.g., Hung 2000; Chen et al. 2006; Dong et al. 2009; Chen et al. 2014; Kuo et al. 2015), often produce severe landslides in the mountains.. The 2025 M s 6.4 Dapu earthquake triggered landslides on numerous places near its epicenter in Chiayi and Tainan (e.g., Li et al. 2025; Wang et al. 2025). In addition to geological conditions, a problem is deserved for solving: Could the focal mechanism of an earthquake influence the triggering of landslides? Of course, to study the mechanisms and hazards of landslides should also be an important issue in Taiwan. Fourthly, the seismic-wave velocities in the shallow depths are lower in the Western Coastal Plain than in the Western Foothills (e.g., Rau et al. 1995; Ma et al. 1996; Kim et al. 2006; Wu et al. 2007; Kuo-Chen et al. 2012). Low-velocity, thick sedimentary layers can yield stronger nonlinear effects than high-velocity, thin rock layers (e.g., Boore and Joyner 1997; Tsai and Huang 2000; Dalguer et al. 2001; Wang et al. 2002; Huang et al. 2005, 2007, 2009; Chan and Stein 2009; Guéguen et al. 2019). The nonlinear effects, including strong site amplification, liquefaction, etc., may strengthen the surface ground motions (cf. Chen et al. 2025; Su et al. 2025), thus being able to yield more damage. Fifthly, the seismic-wave attenuation, i.e., the Q-value, can affect seismic damage. Several researchers (e.g., Chen et al. 1989; Wang 1993; Wang et al. 2010) observed that the Q-values are lower underneath the Western Coastal Plain than below the Western Foothills. Small Q-values will yield a high loss of seismic-wave energy. This will make the seismic waves decay faster in the Western Coastal Plain with low-Q than in the Western Foothills with high-Q. This would lead to lower seismic damage in the former than in the latter. Sixthly, the focal mechanism and rupture directivity of an earthquake could affect the spatial distribution and degree of seismic damage (e.g., Lee et al. 2007; Koketsu et al. 2016). However, these effects cannot be studied for pre-1950 earthquakes because of a lack of data of focal mechanisms and rupture processes. 5. Conclusions We compiled a catalogue of seventy-six larger-sized historical and instrumentally- recorded earthquakes which occurred in the Yunlin-Chiayi-Tainan area from 1644 to 2025. The epicentral distribution of 33 mainshocks with M s ≥5 shows that some mainshocks are clearly correlated with the exposed active faults, yet not for others. For the whole area, the time series of these events may be separated into three time intervals: the first one from No. 1 in 1644 to No. 8 in 1720, the second one from No. 9 in 1721 to No. 20 in 1906, and the third one from No. 21 in 1906 to No. 33 in 2025. The longest and shortest inter-occurrence times between two sequent events were, respectively, 18497 days (50.68 years) and 27 days (0.0074 years). The average inter-occurrence times (or the average recurrence period) are 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years), respectively, for the whole time interval, the first one, the second one, and the third one. The time series for the whole time interval and three respective ones seem to show irregular recurrence behavior with low periodicity. The CV values, which represent the degree of periodicity of time series, are 0.199, 0.347, 0.287, and 0.503 for the whole time interval, the first one, the second one, and the third one, respectively. Hence, the degree of periodicity increased from the first time interval to the second one and then decreased from the second one to the third one. For 33 mainshocks, the number and percentage of mainshocks in a month were the largest and the smallest, respectively, in November and in April. Seismic activities are higher in the wintertime than in the summertime.

Introduction","content":"\u003cp\u003eThe Yunlin-Chiayi-Tainan area (denoted as the YCN area below) is in the southwest part of Taiwan (see Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e). Due to arc-continental collisions (e.g., Hsu 1971; Tsai et al. 1977; Wu 1978; Tsai 1986), Taiwan is specified with high seismic activities and the occurrences of numerous larger-sized earthquakes (see Hsu 1971; Wang et al. 1983; Wang 1988, 1998, 2024; Wang and Shin 1998) produced by strong and complex tectonics. Shyu et al. (2005) considered the YCN area to be under the \u0026lsquo;initial collision.\u0026rsquo; From west to east, three main geological structures in the YCN area (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e) are: the Western Coastal Plain, the Western Foothills, and the Central Range (e.g., Ho, 1988; Shyu et al. 2005; Teng et al. 2005).\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cp\u003eThe Central Geological Survey (GGS, now the Geological Survey and Mining Management Agency), Ministry of Economic Affairs and numerous researchers (e.g., Bonilla 1975, 1977; Hsu and Chang 1979; Lin et al. 2000; Teng et al. 2005; Peng et al. 2004; Shyu et al. 2005, 2016; Chen et al. 2006) have recognized several main earthquake faults in the YCN area. Figure\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e shows several first-class active faults: the Chukou fault (denoted as CKF), the Chiuchiungkeng fault (denoted as CCKF), the Meishan fault (denoted as MSF), the Muchiliao fault (denoted as MCLF), the Liuchia fault (denoted as LCF), the Kuohsaioli fault (denoted as KHLF), the Hsinhua fault (denoted as HHF), the Houchiali fault (denoted as HCLF), and the Tsochen fault (denoted as TCF). The Chukou fault seems to be linked with the Chelungpu fault along which the 1999 \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e7.7 Chi-Chi earthquake ruptured.\u003c/p\u003e \u003cp\u003eIn order to help seismologists and geologists to explore numerous seismological problems in the YCN area, it is necessary to compile a catalogue of large earthquakes, consisting of pre-1897 historical events and post-1897 instrumentally-recorded ones. In the Taiwan earthquakes can be seen in many catalogues with different magnitude scales by domestic authors (e.g., Hsu 1961, 1966, 1971, 1980, 1983b; Li 1983; Cheng and Yeh 1989; Wang and Kuo 1995; Cheng et al. 1999, 2002; Chen and Tsai 2008; CMB 2011; Wang 2024, 2025; CMA 2025). Recently, Wang and Chen (2026) compiled a catalogue of earthquakes in the Taichung-Chunghua-Nantou area. A large number of international catalogues also include Taiwan earthquakes (e.g., CMO 1952; Gutenberg and Richter 1954; B\u0026aring;th and Duda 1964; Duda 1965; Roth\u0026eacute; 1969; Lee et al. 1976, 1978; Utsu 1979, 1982 Abe 1981; Abe and Kanamori 1980; Gu 1983; Abe and Noguchi 1983a,b; Theunissen et al. 2010; Aretz 2016).\u003c/p\u003e \u003cp\u003eIn the followings, we will compile a catalogue including historical and instrumentally- recorded larger-sized earthquake in the YCN area based on the above-mentioned catalogues. Of course, the spatial distribution of focal mechanisms of earthquakes is important for a complete catalogue. But, this study cannot be done here because of a lack of focal mechanisms of historical events and many pre-1960 instrumentally-recorded ones. From the catalogue, some basic studies will be done to explore the seismicity in the area. Such studies are the epicentral distribution, time series of earthquakes, and the variation in inter-occurrence time between two sequent events. Irregular recurrence behavior of time series of events is a significant issue (cf. Goes 1996). It is useful to evaluate the numbers of events in respective 12 months of a calendar year. Larger-sized earthquakes often generate seismic damage, including deaths, injuries, buildings collapsed, and buildings damaged. The studies on seismic damage are necessary not only for scientific interests but also for social needs.\u003c/p\u003e"},{"header":"2.

Before the installation of seismometers, the events are named the \u0026lsquo;historical earthquakes\u0026rsquo; in this study. The seismic intensity has been long used to represent the size or strength of an earthquake, especially for a historical event (e.g., Davison 1921; Richter 1958; Hsu 1979). The seismic intensity is a measure of the degree of ground motions that local people can feel, or the degree of damage for houses, buildings, and civil structures under vibrations. In 1883, Giuseppe Mercalli (an Italian volcanologist) first formulated the intensity scale. Since then, several intensity scales have been developed to quantify earthquakes. The Japanese also constructed their intensity scale. Kawasumi (1943) first applied the seismic intensity to define intensity magnitude, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eK\u003c/em\u003e\u003c/sub\u003e, for quantifying earthquakes in Japan. Kawasumi (1951) also correlated \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eK\u003c/em\u003e\u003c/sub\u003e to the local magnitude for Japanese earthquakes. The Central Metrological Observatory (CMO, now the Japan Meteorological Agency), Japan reported historical earthquakes in Japan and Taiwan (see CMO 1952) by using a magnitude scale of \u003cem\u003eM\u003c/em\u003e\u0026thinsp;=\u0026thinsp;4.85\u0026thinsp;+\u0026thinsp;0.5\u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eK\u003c/em\u003e\u003c/sub\u003e to quantify an event. However, several authors (e.g., Wang and Miyamura 1990; Wang et al. 1990) did not consider this magnitude scale to be appropriate for Taiwan earthquakes.\u003c/p\u003e \u003cp\u003eIn 1897, the Japanese installed the first seismometer at Taipei (cf. Wang 1998). Hence, this year is an important one to separate Taiwan earthquakes into historical (pre-1897) events and instrumentally-recorded (post-1897) ones. For a historical earthquake in Taiwan, Hsu (1961) first used the empirical formulas (Gutenberg, 1945; Gutenberg and Richter 1942, 1956): \u003cem\u003er\u003c/em\u003e\u0026thinsp;=\u0026thinsp;2.3(\u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eGR\u003c/em\u003e\u003c/sub\u003e-1.3)\u003csup\u003e3\u003c/sup\u003e-1.7 or \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eGR\u003c/em\u003e\u003c/sub\u003e=[(\u003cem\u003er\u003c/em\u003e\u0026thinsp;+\u0026thinsp;1.7)/2.3]\u003csup\u003e1/3\u003c/sup\u003e to quantify Taiwan earthquakes. In the empirical formulas, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eGR\u003c/em\u003e\u003c/sub\u003e is Gutenberg\u0026rsquo;s (1945) surface-wave magnitude and \u003cem\u003er\u003c/em\u003e is the radius (in km) of the felt area to be considered as a circle.

In order to estimate the magnitude values of some historical events, Tsai (1985) compared the spatial distribution of damage produced by a historical event with that generated by a post-1900 event whose location was near the historical one. When the two spatial distributions are similar, the magnitude of the post-1900 event was taken by him to be that of the historical one. Tsai\u0026rsquo;s magnitude scale is denoted as \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eT\u003c/em\u003e\u003c/sub\u003e. Of course, there are some problems with the method. Due to the differences on the numbers of buildings, building structures, landslides etc. between the pre-1900 era and the post-1900 era, his method to estimate the magnitude of a historical event is questionable.\u003c/p\u003e \u003cp\u003eHsu (1961, 1966, 1971) first reported numerous historical earthquakes. Hsu (1980) compiled larger-sized historical events from 1644 to 1896. A catalogue of Taiwan earthquakes (including the occurrence dates, possible occurrence localities or areas, and damage of events) during 1682\u0026minus;1895 was compiled by Hsu (1983a) from historical documents. According to this catalogue and related information, Hsu (1983b) and Tsai (1985) anlyzed historical earthquakes and their damage.

Instrumentally-recorded Earthquakes\u003c/h2\u003e \u003cp\u003eAs mentioned above, the Taiwan earthquakes have been instrumentally recorded since 1897 (cf. Wang 1989, 1998, 2024). For instrumentally-recorded earthquakes, an important parameter to quantify the size of an event is the \u0026lsquo;magnitude\u0026rsquo; which is measured from the amplitudes of seismograms. The local magnitude, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eL\u003c/em\u003e\u003c/sub\u003e. which was defined by Richter (1935) has been used to quantify an earthquake from local seismograms. Since Gutenberg (1945) proposed surface-wave magnitude, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eGR\u003c/em\u003e\u003c/sub\u003e, this magnitude scale was very important for quantifying earthquakes before 1963. In the early 1960's, the World-Wide Standard Seismographic Network (WWSSN) was constructed by the United States Coast and Geodetic Survey (USG\u0026amp;GS), USA for monitoring the global earthquakes. From the seismograms recorded by the WWSSN, the surface-wave magnitude, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e, is evaluated by using the \"Prague-Moscow formula\" (Venek et al. 1962): \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e=log(\u003cem\u003eA\u003c/em\u003e/\u003cem\u003eT\u003c/em\u003e)\u0026thinsp;+\u0026thinsp;1.66log\u003cem\u003eΔ\u003c/em\u003e\u0026thinsp;+\u0026thinsp;3.3 where \u003cem\u003eA\u003c/em\u003e is the maximum trace surface-wave amplitudes, \u003cem\u003eT\u003c/em\u003e is the period (=\u0026thinsp;20\u0026thinsp;\u0026plusmn;\u0026thinsp;2 sec) of the peak amplitude, and \u003cem\u003eΔ\u003c/em\u003e is the epicentral distance in degrees. Since 1966, this formula has been accepted by the International Association of Seismology and Physics of Earth's Interior (IASPEI) to quantify earthquakes.\u003c/p\u003e \u003cp\u003eNumerous international governmental agencies routinely determine the magnitudes of global earthquakes, including Taiwan\u0026rsquo;s larger-sized ones. Of course, numerous researchers compiled the earthquakes. Those agencies and researchers used different magnitude scales to quantify earthquakes. The CMO (now the JMA) determined the magnitudes of earthquakes in Japan and Taiwan by using the formula (Tsuboi 1951): \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eJ\u003c/em\u003e\u003c/sub\u003e=log\u003cem\u003eA\u003c/em\u003e\u0026thinsp;+\u0026thinsp;l.731log\u003cem\u003eΔ\u003c/em\u003e-0.83. In this formula, \u003cem\u003eA\u003c/em\u003e (in \u0026micro;m) is either the larger value of the maximum amplitudes of seismograms along two horizontal components or the composite one of the two maximum amplitudes and \u003cem\u003eΔ\u003c/em\u003e is the epicentral distance (in km). CMO\u0026rsquo;s catalogue includes the earthquakes of the YCN area from 1902 to 1927. Utsu (1979, 1982) compiled a catalogue to include numerous Taiwan earthquakes. The magnitude values of Utsu\u0026rsquo;s catalogue for the events from 1885 to 1950 were taken from CMO (1952). He evaluated the magnitude values of events from 1951 to 1980 by using the amplitudes measured from the seismograms recorded by the JMA\u0026rsquo;s Wiechert seismographs based on Tsuboi\u0026rsquo;s formulae. Utsu\u0026rsquo;s magnitude scale is denoted by \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eU\u003c/em\u003e\u003c/sub\u003e in this study. Essentially, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eU\u003c/em\u003e\u003c/sub\u003e is equivalent to \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eJ\u003c/em\u003e\u003c/sub\u003e. Utsu\u0026rsquo;s catalogue includes the earthquakes of the YCN area from 1904 to 1964.\u003c/p\u003e \u003cp\u003eHsu (1961) first reported disastrous events from 1900 to 1960. Hsu (1971, 1980, 1985) quantified Taiwan earthquakes during 1934\u0026minus;1980 from the data observed by the Taiwan Weather Bureau (TWB) and the Central Weather Bureau (CWB, now the Central Weather Administration, CWA) based on Hsu\u0026rsquo;s formula: \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eH\u003c/em\u003e\u003c/sub\u003e=log\u003cem\u003eA\u003c/em\u003e\u0026thinsp;+\u0026thinsp;l.09log\u003cem\u003eΔ\u003c/em\u003e\u0026thinsp;+\u0026thinsp;0.50. From the formulas in use, \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eH\u003c/em\u003e\u003c/sub\u003e is different from \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eJ\u003c/em\u003e\u003c/sub\u003e (cf. Wang and Miyamura, 1990; Wang, 1992). Although the definitions of Hsu\u0026rsquo;s magnitude scale for historical earthquakes and instrumentally-recorded ones are different, they are both denoted by \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eH\u003c/em\u003e\u003c/sub\u003e here for convenience purposes. Hsu (1971, 1980, 1985) did not quantified the instrumentally-recorded events during 1897\u0026minus;1933. This is due to two reasons: (1) the number of seismic stations was very small before 1934; and (2) the quality of pre-1934 seismograms was not good and some seismograms were disturbed or lost during the Second World War. Hence, He could only take the magnitude values from other catalogues.\u003c/p\u003e \u003cp\u003eTaiwan earthquakes were quantified in numerous domestic catalogues with different magnitude scales. Hsu (1971) published the first catalogue consisting of \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eH\u003c/em\u003e\u003c/sub\u003e\u0026ge;4 earthquakes during 1936\u0026ndash;1967. Hsu (1980) renewed the catalogue by correcting the events during 1936\u0026ndash;1979 and adding several instrumentally-recorded ones during 1900\u0026ndash;1936. Li (1983) compiled a catalogue of earthquakes with magnitudes\u0026thinsp;\u0026ge;\u0026thinsp;5. Cheng and Yeh (1989) compiled a catalogue of instrumentally-recorded \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eL\u003c/em\u003e\u003c/sub\u003e\u0026ge;4 events (\u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eL\u003c/em\u003e\u003c/sub\u003e=local magnitude) during 1898\u0026ndash;1988. from Hsu's catalogue and the catalogue published by the Institute of Earth Sciences (IES), Academia Sinica. They conversed several magnitude scales into the local magnitude.\u003c/p\u003e \u003cp\u003eSeveral authors (e.g., Gutenberg and Richter 1954; B\u0026aring;th and Duda 1964; Duda 1965; Roth\u0026eacute; 1969; Lee et al. 1978; Abe and Kanamori 1980; Abe and Noguchi 1983a,b; Abe 1981, 1988; Gu 1983; Li 1983; Aretz 2016) reported the magnitudes of Taiwan earthquakes.

Lee et al. (1978) compiled their catalogue by taking the data from 15 catalogues with different magnitude scales. Hence, the magnitude scale of their catalogue is quite complicated and thus simply denoted as \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003eLee\u003c/em\u003e\u003c/sub\u003e in this study. Since Gu\u0026rsquo;s (1983) catalogue was not cited by Lee et al. (1978), the magnitude values of Gu\u0026rsquo;s catalogue are also used this study. The time periods of reporting the earthquakes of the YCN area are from 1927 to 1941 for Gutenberg-Richter\u0026rsquo;s catalogue, from 1904 to 1941 for Abe and co-authors\u0026rsquo; catalogue, from 1661 to 1964 for Gu\u0026rsquo;s catalogue, from 1904 to 1964 for Lee et al.\u0026rsquo;s catalogue, from 1906 to 1941 for Duda\u0026rsquo;s catalogue, and only the year 1964 for Roth\u0026eacute;\u0026rsquo;s catalogue.\u003c/p\u003e \u003cp\u003eSome other authors (e.g., Engdahl et al. 1998; Engdahl and Villaseňor 2002; Theunissen et al. 2010) relocated or revised the locations of some Taiwan earthquakes from different sources.

This question is due to a fact that this large event did not cause seismic damage in Tainan which was a big city in 1902. There could be two reasons to explain why such a large earthquake did not cause damage. The first reason is that like two 1906 earthquakes as mentioned above, the magnitude value of 1902 event published by CMO could be over-estimated. The second reason is that the location of the earthquake determined by the CMO might be incorrect, and it could be somewhat far away from the Tainan harbor and located at the Taiwan Strait. This would decrease the possibility of producing damage. A significant example to explain this problem is the September 16, 1994 Ms7.3 earthquake which occurred at the Taiwan Strait offshore Tainan (cf. Chen et al. 1996). This event did not produce seismic damage in southwest Taiwan. The two reasons might be due to incomplete data for determining the magnitude value and location in 1902 when the seismic stations were very few and almost located in northern Taiwan.\u003c/p\u003e"},{"header":"4. Some results and discussion","content":"\u003cp\u003eTo consider the scope and length of this study, we will only focus on the mainshocks of the YCN area in the following studies.

The larger the event is, the bigger the circle is. The first-class active faults recognized by the CGS in the area are also shown in the figure. Since the magnitude values and localities of nine historical earthquakes (including the mainshocks of earthquake sequences) have not yet estimated, they are not plotted in Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e.\u003c/p\u003e \u003cp\u003eFigure \u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e shows the localities of mainshocks, including 16 historical events and 17 instrumentally-recorded ones. Some of them have a high correlation with the exposed active faults. Nos. 12 and 20 were near the Meishan fault (MF). No. 28 was near the Tachienshan fault (TCSF). No. 07 was to the south of the Chukou fault (CKF). Nos. 08 and 25 were to the Muchiliao fault (MCLF). No. 24 was close to the Liuchia fault (LCF). No. 27 was on the Hsinhua fault (HHF). No. 09 was to the east of and near the Houchiali fault (HCLF). Of course, we cannot find the relation between the exposed active faults with other mainshocks. The sediments are generally thick in the area from geological surveys (cf. Ho 1988; Teng et al. 2005) and from the 3D seismic tomography (e.g., Rau and Wu 1995; Ma et al. 1996; Kim et al. 2005; Wu et al. 2007; Kuo-Chen et al. 2012). The related active faults might be below the sediments and thus hidden.

The time difference between the two events is \u0026sim;114 years. Since up to date there has been 120 years from the occurrence of the 1906 Meishan earthquake, this time difference is longer than 114 years. Hence, we should much pay attention to the possibility of the occurrence of the next Meishan earthquake in the near future.

Nevertheless, we should still watch the possibility of the occurrence of a larger-sized earthquake on and near the Tainan City in the near future.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec8\" class=\"Section2\"\u003e \u003ch2\u003e4.2 Time series of the mainshocks\u003c/h2\u003e \u003cp\u003eThe time series of 33 mainshocks and the largest events of earthquake sequences are displayed in Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e: the dotted lines for historical earthquakes and the solid lines for instrumentally-recorded events. There are several groups of earthquakes with short inter-occurrence times. Since the lines related to them are much closer to one another, they cannot be separated very well and thus the lines become wider. On the other hand, the lines for events with long inter-occurrence times separate very much. In addition, the degree of clustering remarkably seems to be lower for historical earthquakes than for instrumentally- recorded ones. The number (=\u0026thinsp;16) of historical earthquakes that occurred from 1644 to 1895 (i.e., a longer time period of 252 years) is smaller than that (=\u0026thinsp;17) of instrumentally-recorded events from 1902 to 2025 (i.e., a shorter time period of 124 years). Figure\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e displays an increase in seismic activity of larger events from the first time period to the second one. This increase is important for prediction and forecasting of earthquakes in the area. However, the reasons to produce such an increase are not yet known. In order to mitigate seismic hazards, Taiwan\u0026rsquo;s seismologists and geologists should pay attention to this problem.\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cp\u003eFigure \u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e obviously demonstrates irregular recurrence behavior with weak periodicity for earthquakes in the YCN area.

The longest and shortest inter-occurrence times between two sequent events are, respectively, 18497 days (50.68 years) and is 27 days (0.0074 years). Three time intervals can be delineated from the time series: the first one from No. 1 in 1644 to No. 8 in 1720, the second one from No. 9 in 1721 to No. 20 in 1906, and the third one from No. 21 in 1906 to No. 33 in 2025. The average inter-occurrence times (denoted as \u003cem\u003e\u0026micro;\u003c/em\u003e), which can be considered as the average recurrence period or repeat time. The values for the whole time interval, the first, second, and the third time intervals are, respectively, 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years). The average value for the whole time interval is displayed by a thin solid horizontal line and those for the three respective time intervals shown by three thin dotted horizontal lines in Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e. The values of \u003cem\u003e\u0026micro;\u003c/em\u003e increased from the first time interval (1964\u0026minus;1720) to the second one (1720\u0026minus;1906), and then decreased from the second one to the third one (1906\u0026minus; 2025).\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cp\u003eThe average inter-occurrence time for the whole time interval is longer than those for the first and third time intervals and shorter than that for the second time interval. The average inter-occurrence times increased from the first time interval to the second one, and then decreased from the second one to the third one. This provides indirect evidence of irregular recurrence behavior of earthquakes in the YCN area. The mechanisms to result in this phenomenon are not yet known It is necessary to make more studies on the mechanisms. Such irregular recurrence behavior could decrease the possibility of long-term prediction or forecasting of \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e\u0026ge;5 earthquakes in the YCN area.\u003c/p\u003e \u003cp\u003eIn order to statistically investigate the temporal variation in earthquakes, we may consider a method of calculating the coefficient of variation (\u003cem\u003eCV\u003c/em\u003e) (cf. Forkman 2009). This coefficient is \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;=\u0026thinsp;\u003cem\u003eσ\u003c/em\u003e/\u003cem\u003e\u0026micro;\u003c/em\u003e where \u003cem\u003eσ\u003c/em\u003e is the standard deviation and \u003cem\u003e\u0026micro;\u003c/em\u003e is the mean for a sample of data. This value expresses the extent of variability related to the mean of the population. A distribution of data has normal-variance as \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;=\u0026thinsp;1 or \u003cem\u003eσ\u003c/em\u003e\u0026thinsp;=\u0026thinsp;\u003cem\u003e\u0026micro;\u003c/em\u003e. A distribution of data is completely periodic as \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0 or \u003cem\u003eσ\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0. A distribution of data has considered to be low-variance or low-periodicity as \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;0 and high-variance or aperiodicity was \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;\u0026gt;\u0026thinsp;1 (e.g., Goes 1996; Satake 2015). For a time series of earthquakes, the meaning of \u003cem\u003eCV\u003c/em\u003e is: \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0 for the periodicity, \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;1 for the low periodicity, and \u003cem\u003eCV\u003c/em\u003e\u0026thinsp;\u0026gt;\u0026thinsp;1 for the aperiodicity. An increase in \u003cem\u003eCV\u003c/em\u003e from 0 to 1 leads to a decrease in degree of periodicity.\u003c/p\u003e \u003cp\u003eFor the whole time interval, the first one, the second one, and the third one, the values of \u003cem\u003eCV\u003c/em\u003e are, respectively, 0.199, 0.347, 0.287, and 0.503 because of the respective values of \u003cem\u003eσ\u003c/em\u003e, i.e., 862.52 days, 1208.62 days, 1618.99 days, and 1618.41 days as based on the above-mentioned values of \u003cem\u003e\u0026micro;\u003c/em\u003e. Results indicate that degree of periodicity is the highest in the whole time interval. The \u003cem\u003eCV\u003c/em\u003e value is the largest for the third time interval (1906\u0026minus;2025), the middle for the first time interval (1644\u0026minus;1720), and the smallest for the second one (1720\u0026minus;1906). In other words, the degree of periodicity increases from the first time interval to the second one, and then decreases from the second one to the third one. Hence, since 1906 the periodicity of earthquake occurrences has been the lowest and the degree of irregular recurrence behavior the highest in the YCN area.

\u003cp\u003eThere are three types of factors in producing different degrees of seismic damage. The first type is the social factor. This includes two components: First, the numbers of population, houses, buildings, and civil structures were much larger after 1900 than before 1900. Secondly, the emergency response (or resiliency) was weaker before 1900 than after 1900. The second type is the engineering factor, including two components. The first component is the quality (i.e., structural vulnerability or fragility) of houses, buildings, and civil structures, which was much higher after 1900 than before 1900. The second component is the extent and density of built environment (i.e., exposure). The exposure should change very much from the ancient time to the recent one. The two type of factors could yield higher seismic damage before 1900 than after 1900.\u003c/p\u003e \u003cp\u003eThe third type is the geological-seismological factor. Although this factor is originally controlled by the \u0026lsquo;nature,\u0026rsquo; the previous two factors can also influence it. The human beings have harmed the Earth very much. This factor includes several components as mentioned below. First, the geological conditions are important on yielding seismic damage. Geological surveys show that the Western Coastal Plain and the Western Foothills are, respectively, to the west and to the east of the YCN area (cf. Ho 1988; Teng et al. 2005). The Tachienshan fault (TCSF) and the Chukou fault (CKF) are almost along the western boundary of the Western Foothills. The sedimentary layers are much thicker underneath the Western Coastal Plain than below the Western Foothills in the YCN area. This would strongly affect the spatial distribution of seismic damage.\u003c/p\u003e \u003cp\u003eSecondly, large earthquakes could produce remarkable deformations and ground surface ruptures and fissures which can directly and indirectly result in seismic damage. For example, the 1964 Baihe earthquake caused many deformations and ground surface ruptures and fissures (cf. Hsu and Lu 1969) which caused seismic damage. The 2025 \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e6.4 Dapu earthquake produced co-seismic deformations (e.g., Lee et al. 2025; Lu et al. 2025; Sharma et al. 2025).\u003c/p\u003e \u003cp\u003eThirdly, large earthquakes, especially the shallow ones, for example, the 1999 \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e7.7 Chi-Chi earthquake (e.g., Hung 2000; Chen et al. 2006; Dong et al. 2009; Chen et al. 2014; Kuo et al. 2015), often produce severe landslides in the mountains.. The 2025 \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e6.4 Dapu earthquake triggered landslides on numerous places near its epicenter in Chiayi and Tainan (e.g., Li et al. 2025; Wang et al. 2025). In addition to geological conditions, a problem is deserved for solving: Could the focal mechanism of an earthquake influence the triggering of landslides? Of course, to study the mechanisms and hazards of landslides should also be an important issue in Taiwan.\u003c/p\u003e \u003cp\u003eFourthly, the seismic-wave velocities in the shallow depths are lower in the Western Coastal Plain than in the Western Foothills (e.g., Rau et al. 1995; Ma et al. 1996; Kim et al. 2006; Wu et al. 2007; Kuo-Chen et al. 2012). Low-velocity, thick sedimentary layers can yield stronger nonlinear effects than high-velocity, thin rock layers (e.g., Boore and Joyner 1997; Tsai and Huang 2000; Dalguer et al. 2001; Wang et al. 2002; Huang et al. 2005, 2007, 2009; Chan and Stein 2009; Gu\u0026eacute;guen et al. 2019). The nonlinear effects, including strong site amplification, liquefaction, etc., may strengthen the surface ground motions (cf. Chen et al. 2025; Su et al. 2025), thus being able to yield more damage.\u003c/p\u003e \u003cp\u003eFifthly, the seismic-wave attenuation, i.e., the Q-value, can affect seismic damage. Several researchers (e.g., Chen et al. 1989; Wang 1993; Wang et al. 2010) observed that the Q-values are lower underneath the Western Coastal Plain than below the Western Foothills. Small Q-values will yield a high loss of seismic-wave energy. This will make the seismic waves decay faster in the Western Coastal Plain with low-Q than in the Western Foothills with high-Q. This would lead to lower seismic damage in the former than in the latter.\u003c/p\u003e \u003cp\u003eSixthly, the focal mechanism and rupture directivity of an earthquake could affect the spatial distribution and degree of seismic damage (e.g., Lee et al. 2007; Koketsu et al. 2016). However, these effects cannot be studied for pre-1950 earthquakes because of a lack of data of focal mechanisms and rupture processes.\u003c/p\u003e \u003c/div\u003e"},{"header":"5. Conclusions","content":"\u003cp\u003eWe compiled a catalogue of seventy-six larger-sized historical and instrumentally- recorded earthquakes which occurred in the Yunlin-Chiayi-Tainan area from 1644 to 2025. The epicentral distribution of 33 mainshocks with \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e\u0026ge;5 shows that some mainshocks are clearly correlated with the exposed active faults, yet not for others. For the whole area, the time series of these events may be separated into three time intervals: the first one from No. 1 in 1644 to No. 8 in 1720, the second one from No. 9 in 1721 to No. 20 in 1906, and the third one from No. 21 in 1906 to No. 33 in 2025. The longest and shortest inter-occurrence times between two sequent events were, respectively, 18497 days (50.68 years) and 27 days (0.0074 years). The average inter-occurrence times (or the average recurrence period) are 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years), respectively, for the whole time interval, the first one, the second one, and the third one. The time series for the whole time interval and three respective ones seem to show irregular recurrence behavior with low periodicity. The \u003cem\u003eCV\u003c/em\u003e values, which represent the degree of periodicity of time series, are 0.199, 0.347, 0.287, and 0.503 for the whole time interval, the first one, the second one, and the third one, respectively. Hence, the degree of periodicity increased from the first time interval to the second one and then decreased from the second one to the third one. For 33 mainshocks, the number and percentage of mainshocks in a month were the largest and the smallest, respectively, in November and in April. Seismic activities are higher in the wintertime than in the summertime.\u003c/p\u003e "},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eDATA AND RESOURCES\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe data used in this study can be requested through the Central Weather Administration (CWA) website (\u003cspan class=\"ExternalRef\"\u003e\u003cspan class=\"RefSource\"\u003ehttps://gdms.cwa.gov.tw/catalogDownload.php\u003c/span\u003e\u003c/span\u003e).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDECLARATION OF COMPETING INTEREST\u003c/strong\u003e\u003cstrong\u003eS\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe authors declare that the research was conducted without any commercial or financial relationships of potential conflict of interest.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunding Declaration\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eNo.\u003c/p\u003e\u003ch2\u003eAuthor Contribution\u003c/h2\u003e\u003cp\u003eJHW carried out the calculations and drafted the manuscript.

There are seventy-six events, including 33 mainshocks of earthquake sequences and the sequences of moderate events. The epicenters of some of mainshocks with \u003cem\u003eM\u003c/em\u003e\u003csub\u003e\u003cem\u003es\u003c/em\u003e\u003c/sub\u003e\u0026ge;5 are related to the exposed active faults, yet not for others. Irregular recurrence behavior with low periodicity exists in the time series of 33 mainshocks. Such a time series can be divided into three time intervals. The longest and shortest inter-occurrence time between two sequent events are, respectively, 18497 days (50.68 years) and 27 days (0.0074 years). The average inter-occurrence times (or the recurrence period) for the whole time interval, the first one, the second one, and the third one are, respectively, 4339.88 days (11.89 years), 3489.50 days (9.55 years), 5635.33 days (15.44 years), and 3612.67 days (9.89 years). The values of coefficient of variation vary from 0.199 to 0.503, thus indicating low periodicity of earthquake occurrences. The largest and smallest numbers and percentages of mainshocks in a month appear, respectively, in November and in April. The seismic activities are lower in the summertime than in the wintertime.\u003c/p\u003e","manuscriptTitle":"A Catalogue of Larger-sized Earthquakes in the Yunlin-Chiayi-Tainan Area, Taiwan","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-04-27 14:30:45","doi":"10.21203/rs.3.rs-9391031/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"editorInvitedReview","content":"","date":"2026-05-04T08:39:59+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"267130974529764835003406077500824249846","date":"2026-04-29T08:10:32+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2026-04-19T07:48:40+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-04-14T02:54:28+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-04-13T07:33:06+00:00","index":"","fulltext":""},{"type":"submitted","content":"Terrestrial, Atmospheric and Oceanic Sciences","date":"2026-04-12T01:21:00+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"terrestrial-atmospheric-and-oceanic-sciences","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"taoj","sideBox":"Learn more about [Terrestrial, Atmospheric and Oceanic Sciences](https://link.springer.com/journal/44195)","snPcode":"44195","submissionUrl":"https://submission.springernature.com/new-submission/44195/3","title":"Terrestrial, Atmospheric and Oceanic Sciences","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Springer Open","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"d0a5b91b-211d-46ce-885c-5352e122f511","owner":[],"postedDate":"April 27th, 2026","published":true,"recentEditorialEvents":[{"type":"editorInvitedReview","content":"","date":"2026-05-04T08:39:59+00:00","index":13,"fulltext":""}],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-04-27T14:30:45+00:00","versionOfRecord":[],"versionCreatedAt":"2026-04-27 14:30:45","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-9391031","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-9391031","identity":"rs-9391031","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
