説明
Statistical earthquake analysis, that is represented, for example, by the Gutenberg-Richter relation (GR; Gutenberg and Richter,1944) and by historical and/or instrumentally observed seismicity, plays an important role in seismic hazard assessment, especially to answer the fundamental question of whether large and small earthquakes are related. The aims of this report are: (1) to make compiled data sets of historical earthquake records, instrumentally observed seismicity, and seismogenically active faults from the viewpoint of seismotectonic provinces in Japan (Kakimiet al.,2003); (2) to show the GR relation for each seismotectonic province, in order to discuss the continuity of magnitude-frequency distributions for different sources; and (3) to make reference data sets of instrumentally observed seismicity, cross-referenced to distance from active faults. The magnitudefrequency distributions for the inland seismotectonic provinces form several groups, based on the relation between instrumentally observed seismicity, the historical earthquake record, and active fault data.
