The results show that optimizing boundary conditions and appropriately increasing the width-to-height ratio of the model can significantly improve simulation accuracy, providing a reliable basis for seismic micro-zonation mapping. Complex terrains have a substantial influence on seismic wave propagation and amplification, with higher amplification factors observed in central areas under steep slopes. Increasing the overburden thickness generally reduces acceleration amplification factors. Additionally, different seismic waves exhibit distinct amplification patterns under the same slope angle, which is related to wave frequency and site resonance. Comparisons reveal that the one-dimensional equivalent linear program underestimates amplification effects compared to multi-dimensional methods, especially for specific width-to-height ratios. This study provides a scientific basis for site assessment and design, enhances the understanding of seismic wave behavior in complex terrains, and aids in seismic disaster prevention and mitigation.

amplification in complex terrains. The results show that optimizing boundary conditions and appropriately increasing the width-to-height ratio of the model can significantly improve simulation accuracy, providing a reliable basis for seismic micro-zonation mapping. Complex terrains have a substantial influence on seismic wave propagation and amplification, with higher amplification factors observed in central areas under steep slopes. Increasing the overburden thickness generally reduces acceleration amplification factors. Additionally, different seismic waves exhibit distinct amplification patterns under the same slope angle, which is related to wave frequency and site resonance. Comparisons reveal that the one-dimensional equivalent linear program underestimates amplification effects compared to multi-dimensional methods, especially for specific width-to-height ratios. This study provides a scientific basis for site assessment and design, enhances the understanding of seismic wave behavior in complex terrains, and aids in seismic disaster prevention and mitigation.\u003c/p\u003e","manuscriptTitle":"New Valley Site Seismic Response Simulation Method and Application Validation for Seismic Zoning","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-13 08:30:54","doi":"10.21203/rs.3.rs-7252009/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"reviewerAgreed","content":"","date":"2025-11-05T07:04:27+00:00","index":0,"fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-03T10:44:40+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"Natural Hazards","date":"2025-08-11T06:43:16+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-08-01T07:48:13+00:00","index":"","fulltext":""},{"type":"submitted","content":"Natural Hazards","date":"2025-07-31T04:08:04+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"natural-hazards","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"nhaz","sideBox":"Learn more about [Natural Hazards](https://www.springer.com/journal/11069)","snPcode":"11069","submissionUrl":"https://submission.nature.com/new-submission/11069/3","title":"Natural Hazards","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"85556ba0-9596-4462-9670-d7e3572f5f09","owner":[],"postedDate":"November 13th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2025-11-13T08:30:55+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-13 08:30:54","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7252009","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7252009","identity":"rs-7252009","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
