This research will study the detailed source processes of the Loma Prieta earthquake using a combined teleseismic data set including teleseismic broad-band and short-period body waves and strong motion data near the source. To simulate the highest frequency energy radiated by the mainshock, the research will include the analysis of aftershocks used as empirical Green's functions. By means of this technique, details of the main shock rupture surface will be mapped. This research is a component of the National Earthquake Hazard Reduction Program.

本研究将利用远震宽带短周期体波和震源附近强震数据相结合的远震数据集，研究洛马·普里塔地震的详细震源过程。为了模拟主震辐射的最高频率能量，研究将包括作为经验格林函数的余震分析。利用这种技术，可以绘制出主震破裂面的细节。这项研究是国家减少地震危害计划的一个组成部分。
