Rupture Modes of Fault Systems - An Aid in Interpreting Geological and Earthquake Recurrence Data

9725772 Ward这项研究涉及对断层系统破裂的计算机模拟，结合了地震应力传递的物理学，并受到优秀但有限的地质和地震数据体的约束。通过这种方法，地震观测目录可以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、静力和预应力以及摩擦规律参数的关系。这项研究的成果在解决与震源特征有关的基本问题和与理解地质实地数据和量化地震复发统计有关的实用问题方面应具有价值。这项研究是国家减少地震灾害计划的一部分。***

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. ***
