| 摘 要： | 选取了较为典型的历史震例,并将这些震例的等震线图数字化.利用这些等震线图数据,直接统计出地震参数和震后不同烈度面积之间的关系,并将该关系和烈度衰减几何模型结合起来,反演震后烈度的具体分布形状,以进行震后烈度分布的预测.

| Abstract: | In this paper the isoseisms maps of some typical historic earthquake were digitized. Using these data of isoseisms maps the relation between seismic parameters and post-earthquake areas with different intensities were determined. Based on combination of this relation with geometric attenuation mode of the intensity,the concrete distribution shape of the intensity was inversed and the post-eartquake intensity distribution was predicted. |

| Keywords: | intensity attenuation relation earthquake disaster loss estimate earthquake emergency statistics earthquake intensity isoline |
