Abstract: 

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperity, rise time and rupture velocity on the fault plane. Based on theoretical Green’s function for infinite media, the near-fault pulse is simulated for finite fault model with different faulting specifications. Then, the variations of each fault parameter and site to fault distance on near-fault pulse characteristics are numerically examined and discussed.
