On December 18,1987,an earthquake (M=5.2) of which the epicenter was located about 10km north of Yamaguchi city occurred. We refer to this earthquake as the 1987 Yamaguchiken-Chube Earthquake. In this report, first, an outline of this earthquake and damages of the grounds and structures, etc. are described briefly. Second, studies on the slope stability analysis, the condition on the fall of gravestones, and the acceleration of the ground during the earthquake were performed. As a result, it was shown that the peak surface acceleration developed in Yamaguchi city was in the range of 150-220gal.
