Abstract: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 theory and application of dislocation theory in describing coseismic, interseismic, and postseismic deformation patterns. Then, estimating faults in different earthquake cycle phases is summarized. This study provides support in evaluating seismic risk of a certain fault.
