9725772 Ward This research involves the use of computer simulations of fault system ruptures incorporating the physics of earthquake stress transfer and constrained by excellent, but limited, bodies of geological and seismological data. By this means, the observational catalog of earthquakes can be extended with a deeper perspective on the distribution of earthquakes and seismicity and their relationships to fault segmentation and geometry, static strength and pre-stress, and friction law parameters. Products from this research should be of value in addressing questions that are both fundamental, related to characterization of the earthquake source, and practical, related to the understanding of geological field data and in the quantification of earthquake recurrence statistics. This research is a component of the National Earthquake Hazard Reduction Program. ***

9725772 Ward 这项研究涉及使用断层系统破裂的计算机模拟，结合地震应力传递的物理原理，并受到优秀但有限的地质和地震数据体的约束。 通过这种方式，可以扩展地震观测目录，更深入地了解地震和地震活动的分布及其与断层分段和几何形状、静强度和预应力以及摩擦律参数的关系。 这项研究的产品对于解决与震源特征相关的基本问题和与地质现场数据的理解以及地震复发统计的量化相关的实用问题应该具有价值。 这项研究是国家地震减灾计划的一部分。 ***
