This research is to study earthquake fault behavior and regional deformation by means of newly developed theoretical techniques. These methods invert geodetic elevation changes, triangulation measurements, VLBI baseline data and tide gauge observations to recover the location and intensity of slip on shallow earthquake faults. The goal is to develop quantitative pictures of coseismic, postseismic and interseismic strain accumulation and release. This research is a component of the National Earthquake Hazard Reduction Program.

本研究旨在利用最新发展的理论技术研究地震断层行为和区域形变。这些方法反演大地高程变化、三角测量、VLBI基线数据和验潮仪观测，以恢复浅层地震断层上滑动的位置和强度。其目标是开发同震、震后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。
