Abstract

We compiled a database on fault slip distribution along the 98 major active fault zones in Japan selected for National Seismic Hazard Maps for Japan by The Earthquake Research Committee, the Headquarters for Earthquake Research Promotion, Data were collected from articles and reports on these faults published prior to 2001 as well as‘ Digital Active Fault Map of Japan’ (Nakata and Imaizumi, eds,2002), and then compiled as an Excel file and processed into GIS format. The database contains location, vertical and horizontal displacement and estimated slip rates together with method of measurement of fault-related features and their ages. Each feature is ranked A to D based on its reliability and accuracy. The database on several reverse faults in northeast Japan and strike-slip faults in southwest Japan are graphically represented by Mapinfo, using Shp file of active fault traces of‘ Digital Active Fault Map of Japan’, as well as historical earthquake faults.<BR>This database is the first product of its kind, but is still far from substantial level, especially on slip rate data. However, we believe that this database is useful to roughly locate asperities on active faults for better estimation of strong ground motion.
