The characteristics of the strong ground motion of the 1995 Osaka-Kobe earthquake (M7.2), Japan was analyzed in this paper. The results show that the peak values of horizontal acceleration in epicentral region are about 600~800 gal, the peak value of vertical acceleration is above 300 gal, the duration of the strong ground motion is about 10~15 seconds and the predominant periods is distributed from 0.2 to 2 second. The results of spectrum analysis also show that the amplitude of Fourier spectrum or response spectrum is larger than other records in a wide frequency band.
