摘要

The National Research Institute for Earth Science and Disaster Prevention (NIED) has carried on thespecial research project 'National Seismic Hazard Mapping Project of Japan' to support the preparation ofthe National Seismic Hazard Maps made by the Headquarters for Earthquake Research Promotion. Theseismic hazard maps consist of two kinds of hazard maps. One kind of hazard map is a probabilisticseismic hazard map that shows information predicting possibility that a certain area is attacked by astrong ground motion in a certain term by means of probability. The other kind of hazard map is ascenario earthquake map with a specified seismic fault. As the first step in preparations for producing theseismic hazard maps, which are scheduled to be completed by the end of fiscal year 2004, preliminaryversions of the probabilistic seismic hazard maps for restricted regions and seismic hazard maps forseveral scenario earthquakes have been made. In this article, the outline of methodologies to evaluatestrong-motion distributions both for the probabilistic seismic hazard maps and for the scenario seismichazard maps is presented.
