This research continues three seismotectonic investigations. In the first study, VLBI data are being used to determine regional scale crustal deformation at the North American-Pacific plate boundary. In the second, synthetic earthquake catalogs are being developed using a model of strain accumulation on fault segments and their interactive failure. In the third, geologic data are being used to investigate the evolution of the Santa Cruz mountains and to relate this evolution to North American- Pacific plate motion. The goal of the project is to develop quantitative pictures of coseismic and interseismic strain accumulation and release associated with major faults in western North America. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究继续进行了三次地震构造调查。在第一项研究中，VLBI数据被用来确定北美-太平洋板块边界的区域尺度地壳形变。在第二种情况下，正在利用断层段应变累积及其相互作用破坏的模型来开发合成地震目录。在第三项研究中，地质数据被用来研究圣克鲁斯山脉的演化，并将这种演化与北美-太平洋板块运动联系起来。该项目的目标是开发与北美西部主要断层相关的同震和震间应变积累和释放的定量图像。这项研究是国家减少地震灾害计划的一部分。
