摘要：

This report describes the influence of the seismic source location of interplate earthquake on the evaluation of long-period ground motion in the Tokyo metropolitan area. Source points are arranged at every 10 km in the seismic fault plane on the plate boundary off Ibaraki and Chiba prefecture, along the Sagami and the Suruga Troughs. Reciprocal theorem is applied for the 3-D finite difference method to evaluate ground motions at target sites from many source points. We also examine influence of low-velocity sediments in the Philippine Sea Plate region on long-period ground motions in the Tokyo metropolitan area. © 2021 Architectural Institute of Japan.
