| Abstract: | The 9. 0-magnitude undersea mega-thrust earthquake off the coast of Japan occurred at 14：46 JST on March 11, 2011. The earthquake caused the great casualty and property loss, it also triggered extremely destructive tsunami, which later led to the worst nuclear catastrophe. In this paper, the strong ground motion observation network in Japan is briefly introduced and the strong motion data are preliminarily processed and some statistical characteristics for those data are given and typical response spectrum is calculated. All those processed data could serve the further research. |
