This research is to obtain an estimate of the Loma Prieta earthquake rupture process first by analyzing the teleseismic records and then by simulating strong-motion seismograms. Using records from the new NSF/IRIS PASSCAL seismic instruments that were installed in the aftershock area, the research will involve analysis of aftershock activity including determination of crustal structure near the source region. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究是为了获得估计的洛马普列塔 首先通过分析地震破裂过程， 记录，然后通过模拟强震地震图。 使用 新的NSF/IRIS PASSCAL地震仪器记录， 安装在余震区，研究将涉及 分析余震活动，包括确定 源区附近的地壳结构。 这项研究是一个 国家地震减灾计划的一部分。
