摘要

摘要: 2022年1月8日青海门源M_S6.9地震是该地区有记录以来的第3次强震，未来仍有再次发生强震的可能。基于门源地区的地表高程、速度介质参数以及门源地震断层滑移分布等地形地质特征，采用谱元法精细化模拟青海门源地震的地震波传播过程，重点考察复杂起伏地形区域强地面运动的空间分布特征。结果表明，PGV较大的地方主要集中在断层附近，最大值为53.1 cm/s，且沿断层走向地震响应明显大于垂直断层走向，具有明显的地震方向性效应；地震波在断层两侧出现反应较为剧烈的波前，波场快照PGV可达47.2 cm/s，与实测烈度相近，且模拟给出的烈度分布特征与实测烈度分布规律相同；山体分布密集区域的PGV响应较为剧烈，山体附近的地震动持续时间也较长，而平坦区域的地震响应相对较弱；通过与强震记录对比，验证了本文方法的合理性与准确性。研究成果可为地形复杂山体区域地震预测及防震减灾提供一定的参考。

Abstract: The M_S6.9 Menyuan, Qinghai, earthquake on January 8, 2022 is the third strong earthquake recorded in the region, and it is possible to occur again in the future. Based on the topographical and geological characteristics of the Menyuan region, such as surface elevation, velocity media parameters, and fault slip distribution of the Menyuan earthquake, the spectral element method is used to finely simulate the seismic wave propagation process of the Menyuan earthquake in Qinghai province, and the spatial distribution characteristics of strong ground motion in the region with complex topography are investigated. The results show that the locations with larger PGV are mainly concentrated near the fault, the maximum value is 53.1 cm/s, and the ground motion response along the fault strike is obviously greater than that perpendicular to the fault strike, which shows the significant earthquake directivity effect; The seismic wave has a relatively violent front response on the both sides of fault, the PGV from wave field snapshot can reach 47.2 cm/s, which is close to the measured intensity, and the intensity distribution characteristics derived by simulation are the same as the distribution law of measured intensity; The PGV in the region with dense distribution of mountain is relatively intense, and the ground motion duration near the mountain is also long, while the seismic response in the flat region is relatively weak; The rationality and accuracy of the method proposed in this paper have been verified by comparing the simulated results with the strong earthquake records. The research results can provide a certain reference for the earthquake prediction, the earthquake prevention and disaster reduction in the mountain region with complex topography.
