Development of stochastic heterogeneous slip distribution model for simulation of earthquake ground motion Abe, Hiroyasu; Sekimura, Naoto; Itoi, Tatsuya


Ground motion simulation is an important tool for analyzing seismic risk in engineering systems. Recently, ground motion simulations using fault model are being widely applied. Characterized fault models are conveniently used to model the heterogeneous slip distribution on fault plane, which divides the fault into two areas, i.e., asperity area and background area. The model, however, is too simplified to model the complex characteristics of actual slip. In this paper, a model to simulate the slip distribution of the fault plane is proposed.
