• The Hyogoken-nambu earthquake occurred along active faults in southern Hyogo Prefecture at 5 : 46 on January 17,1995 (JST; JST = GMT + 9h) and caused severe damage to several cities, especially Kobe. We determined the source mechanism and size (seismic moment and magnitude) of the earthquake from analyses of broad-band and strong-motion seismograph data. The source mechanism obtained from a long-period CMT inversion is (strike, dip, slip)=(233°, 83°, 169°) with a small CLVD component (1.5%), Mo = 3.0 × 10^<19>Nm, Mw = 6.9. We compared synthetic strong-motion seismograms computed by application of the reflectivity method to the source mechanism from the long-period CMT inversion with the observed strong-motion seismograms at near distances. We infer that the main shock consisted of 3 subevents that had a seismic moments of 1.5 × 10^<19>Nm (the first subevent), 1.0 × 10^<19>Nm (the second), and 0.5 × 10^<19>Nm (the third).
