QP and QS are estimated through spectral modeling of stations within 300 km, with corner frequencies independently constrained by the empirical Green’s function method to reduce parameter trade-offs. Q values are averaged across channels to examine distance dependence. We find a linear increase in Q with distance for both P and S waves, flattening beyond ~150 km, consistent with a crust–mantle phase transition. Deviations from this trend highlight low-Q zones along the plate boundary, associated with sedimentary basins. These results emphasize the crustal heterogeneity of the region and provide a foundation for future 3-D attenuation models.

We find a linear increase in Q with distance for both P and S waves, flattening beyond ~150 km, consistent with a crust–mantle phase transition. Deviations from this trend highlight low-Q zones along the plate boundary, associated with sedimentary basins. These results emphasize the crustal heterogeneity of the region and provide a foundation for future 3-D attenuation models.\u003c/p\u003e","manuscriptTitle":"Determination of regional attenuation using moderate earthquakes at the Dead Sea fault system","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-14 12:16:01","doi":"10.21203/rs.3.rs-8012036/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-02-04T21:17:13+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-02-04T10:07:56+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"22764228832252761135923983657972425966","date":"2026-01-15T08:37:08+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-11-21T19:23:30+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"305328272169002782458961344872112058726","date":"2025-11-05T17:45:53+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-04T22:37:09+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-11-04T03:46:41+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-11-04T03:45:30+00:00","index":"","fulltext":""},{"type":"submitted","content":"Journal of Seismology","date":"2025-11-02T15:39:08+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"journal-of-seismology","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"jose","sideBox":"Learn more about [Journal of Seismology](http://link.springer.com/journal/10950)","snPcode":"10950","submissionUrl":"https://submission.nature.com/new-submission/10950/3","title":"Journal of Seismology","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"c35ebef4-39bd-447d-baff-8d71fdaf3872","owner":[],"postedDate":"November 14th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-03-23T16:19:22+00:00","versionOfRecord":{"articleIdentity":"rs-8012036","link":"https://doi.org/10.1007/s10950-026-10385-5","journal":{"identity":"journal-of-seismology","isVorOnly":false,"title":"Journal of Seismology"},"publishedOn":"2026-03-20 15:57:50","publishedOnDateReadable":"March 20th, 2026"},"versionCreatedAt":"2025-11-14 12:16:01","video":"","vorDoi":"10.1007/s10950-026-10385-5","vorDoiUrl":"https://doi.org/10.1007/s10950-026-10385-5","workflowStages":[]},"version":"v1","identity":"rs-8012036","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8012036","identity":"rs-8012036","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
