A review on comparison and progress in applications of earthquake dislocation theories based on different models

In this paper， we summarize the theoretical and application research progress of the dislocation theory based on the half-space model and spherical model. And then we discuss the progress of dislocation theory on the study of tsunami and the progress of combining dislocation theory with particle swarm optimization on the study of fault inversion. The advantages and disadvantages of the two dislocation models have been analyzed， meanwhile, the affecting factors of dislocation models in application have been presented. The results show that the application of different dislocation theorys are affected mostly by earth stratification， followed by gravity and curvature， and the influences from topography， focal depth and fault dip are less. All of these factors mentioned above should be considered in application.
