Rupture Characteristics of the 1989 Loma Prieta Earthquake

本研究将研究断裂特征， 利用三种地震波形研究洛马普列塔地震 数据：（1）来自地球观测仪和国际开发协会的极长期数据 全球网络，（2）中期气象数据， WWSSN和GSN网络，以及（3）来自当地的强震数据 站的 将得到的滑移模型与 余震分布和断层模型， 大地测量数据反演 断层几何学分析 断层破裂提供了更好地理解 地震断层作用和地震带上的应变积累 周期 这项研究是国家地震局的一个组成部分。 减少危害方案。

This research will study the rupture characteristics of the Loma Prieta earthquake using three types of seismic waveform data: (1) very-long-period data from the GEOSCOPE and IDA worldwide networks, (2) intermediate-period teleseismic data from the WWSSN and GSN networks, and (3) strong-motion data from local stations. The slip models obtained will be compared with the distribution of aftershocks and with fault models derived from geodetic data inversions. Analysis of fault geometry relative to fault rupture offers the prospect of a better understanding of earthquake faulting and strain accumulation over the seismic cycle. This research is a component of the National Earthquake Hazard Reduction Program.
