1 SEISMIC HAZARD ESTIMATION BASED ON ACTIVE FAULT DATA AND HISTORICAL EARTHQUAKE DATA By Hiroyuki KAMEDA and Toshihiko OKUMURA A method is presented for using historical earthquake data and active fault data jointly for seismic hazard estimation. Japan and its vicinity are divided into 22 regions, and then earthquake occurrence rates are estimated for each region on the basis of information combined from historical earthquakes and active faults. On the basis of simulation results, ground acceleration, iso-seismal maps are developed in terms of peak peak ground velocity, and ground motion duration.
