Clear anti-phase tendency of volcanic eruptions and consistent U.S. Dollar Index response to volcanic forcing

Numerous studies have presented statistical relations between large volcanic eruptions and ensuing El Niño events or between El Niño events and local economies. However, the relation between volcanic eruptions and economies has not been completely clarified. This study compares volcanic eruptions and the U.S. Dollar Index for the past 54 years (1967–2020) to identify significant economic responses to volcanic activity. There is a clear anti-phase tendency between the volcanic eruptions of the western Pacific and those of the eastern Pacific. And volcanic eruptions and U.S. Dollar Index exhibit a strong correlation and U.S. Dollar Index follows the fluctuation trend of volcanic eruptions with a 1-year delay. Thus, results indicate that changes in forces within the earth due to volcanic eruptions continuously impact the global economy. This study identifies a teleconnection between heterogeneous factors that had not been previously reported and provides a new scientific clue regarding the mechanism how has geodynamics affected the human life.
