项目摘要
This research is to study the Loma Prieta earthquake using strong ground motion stations and aftershock recordings to (a) map the variability of the fault zone structure along the rupture zone of the Loma Prieta earthquake to locate fault irregularities controlling rupture initiation, termination, and complexities; (b) incorporate known broad regional three dimensional structure in the modeling of the complete set of strong ground motion data within 50 km of the epicenter to determine whether effects of known three dimensional structure can explain any of the observed variations in intensity of ground motion; and (c) derive corrections to rupture models based on the assumption of plane layered structure.
本研究利用强震台站和余震记录对洛马普列塔地震进行研究,以(A)绘制沿洛马普列塔地震破裂带的断裂带结构的变异性,以定位控制破裂开始、终止和复杂性的断层不规则;(B)将已知的广泛的区域三维结构纳入震中周围50公里范围内的全套强地面运动数据的模拟中,以确定已知的三维结构的影响是否能够解释所观测到的地面运动强度的任何变化;以及(C)根据平面分层结构的假设,对破裂模型进行修正。
