Tectonic Setting of the Kobe Earthquake


Map of Japan showing major plate boundaries (yellow lines) and significant earthquakes (dots) along with the location of the 17 January 1995 shock. Dots show located events during 1961-1994 with size proportional to magnitude and with color coded according to earthquake depth (see scale bar at right of figure). The 17 January earthquake (star) occurred on a northeast-trending strike-slip fault that branches off the Median Tectonic Line, a major right-lateral strike slip fault lying 200 km north of the subduction plate boundary on which great M=8 earthquakes occurred in 1944 and 1946 (rupture zones indicated by red lines).

The above map was prepared by Grant Marshall, USGS.
