Measurement and Interpretation of Crustal Deformation in an Active Fault Zone

提出者将使用一组独特的地壳形变观测数据来创建一幅改进的断裂带运动学图景，从而更好地理解断裂带力学。随着来自GPS测量的此类数据预计将大量增加，现在就有必要利用现有数据，找出我们可以从这些数据中获得什么科学知识，以及收集、组合和解释它们的最佳方式。他们将主要关注加利福尼亚州南部的圣哈辛托断层-这是一个仪器良好的地区，处于两次地震间隔的后期，发生中到大地震的可能性相对较大。

The proposers will use a unique collection of crustal deformation observations to create an improved picture of fault- zone kinematics, and thus better understand fault-zone mechanics. With the vast increase in such data expected from GPS measurements, it makes sense to find out now, using existing data, what science we can get from them and also the best ways of collecting, combining, and interpreting them. They will mostly focus on the San Jacinto fault, in southern California-a well-instrumented area that is in the later part of its interseismic interval, with a moderate-to-large earthquake relatively likely.
