9405533 Ruff This research will systematically study the seismic events that may precede a large earthquake: multiplets, foreshocks, and rupture precursors. In parallel with the earthquake studies, the work will involve the development of simple mechanical models of interaction between stick-slip and creeping portions of the plate interface. The goal of these models is to provide an explanation of observations such as variability in recurrence times, rupture modes, and earthquake size form one earthquake cycle to the next. The overall goal is a systematic study of multiplets, foreshocks, and rupture precursors and how these seismicity features relate to other geologic characteristics in their tectonic setting. This research is a component of the National Earthquake Hazard Reduction Program. ***

9405533本研究将系统地研究可能发生在大地震之前的地震事件：多重地震、前震和破裂前兆。在地震研究的同时，这项工作将涉及开发板块界面粘滑和蠕动部分之间相互作用的简单力学模型。这些模型的目的是为观测结果提供解释，例如从一个地震周期到另一个地震周期，复发时间、破裂模式和地震规模的变异性。总体目标是系统地研究多重地震、前震和破裂前兆，以及这些地震活动特征如何与其构造背景下的其他地质特征相关联。这项研究是国家减少地震灾害计划的一部分。***
