基于大地测量观测的断层运动研究综述

Review of Fault Movement Based on Geodetic Observations

以基于大地测量观测资料研究断层运动为主线,分析讨论地震大地测量观测资料在分析研究断层不同孕震周期运动模式中发挥的作用。回顾断层位错模型的发展,包括弹性回跳理论的提出、位错理论在描述同震、震间和震后形变中的发展应用,总结地震大地测量观测在判断断层孕震阶段中的应用,为断层地震危险性分析提供支撑。

This paper gives a review of fault movement based on geodetic observations. The important role of geodetic observations is discussed in analyzing fault movement in different earthquake cycle phases. First, the evolution of fault movement models is reviewed, including the elastic rebound theo- ry and application of dislocation theory in describing coseismic, interseismic, and postseismic deforma- tion patterns. Then, estimating faults in different earthquake cycle phases is summarized. This study provides support in evaluating seismic risk of a certain fault.
