摘　　要：2011年3月11日日本东太平洋海域发生MW9.0级地震,造成了严重的灾害损失,地震诱发了海啸,海啸灾害最终导致核泄漏事件。本文初步收集整理了日本强震动观测网获得的强震动记录,简要进行强震动记录的特征分析,并完成典型记录的频谱特征计算,为进一步开展全面深入研究地震动特征提供参考。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.
