Strong Motion Simulation of the 1987 Chiba-ken-toho-oki Earthquake (M_J6.7) Using Stochastic Green's Function Generation Method Empirically Considering Surface Waves and Scattering Waves

Abstract

Strong ground motions of the 1987 Chiba-ken-toho-oki earthquake (M_J6.7) are simulated using our revised stochastic Green's function generation method in which surface waves and scattering waves are empirically considered. The source parameters of the asperity model estimated to fit observed and simulated seismic intensity map in the Kanto basin and strong motions of near-by station-pairs have the average feature of previous intraslab earthquakes. The good agreement of simulated strong motions with observed shows the validity of our revised stochastic Green's function generation method.
