| 摘 要： | 对汶川地震序列分析，发现该序列中ML≥5．0级的强余震活动空间上存在明显空段，强余震围绕该空段有反复迁移发生特征。基于上述现象，作者从地震地质和经纬方向余震迁移的角度上做了一些研究，较为定量地为震区预测发震地点提供了简单依据。

| Abstract: | The Wenchuan earthquake sequence is analyzed, and the authors found that the ML ≥95.0 strong aftershoek empty segment obviously existed in the sequence distribution area and that the strong aftershoeks occurred again and again surrounding this empty segment. According to the above mentioned characteristics, the authors researched aftershoek activity from the aspect of earthquake geology and aftershock moving in longitude and latitude direction, more quantificationally providing some simple basis for shock area with estimating strong aftershock location. |
