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.

这项研究是通过分析远程震荡记录，然后通过模拟强动作地震图，以获取对洛马普利塔地震破裂过程的估计。 使用安装在余震区域中的新的NSF/IRIS密封地震仪器中的记录，研究将涉及分析余震活动，包括确定源区域附近的地壳结构。 这项研究是国家地震危害计划的组成部分。
