Abstract
In this study, we performed parametric analyses to examine the fault rupture process and generated earthquake motions near a fault by using three dimensional (3D) finite element method. First, we examined the validity of our method by comparing the work done by Day. Next, the effect of the direction of the rupture propagation were studied. Then, the effect of the length of the fault on the rupture propagation process, magnitude of dislocation on the fault plane, and generated earthquake motions. Finally, the comparison between the results from 3D analyses and those from 2D analyses was made.
