中文摘要：

通过野外考察和地貌变形测量等手段，研究了尼勒克1812年8级地震的地震断层的平面分组特点、活动性质、分段特征，讨论了地震滑塌构造、地震断层与重力滑坡的区别，分析了线性滑坡后壁与地震断层的潜在关系。在正确区分地震断层和滑坡后壁的基础上，确定了地震断层的最大位移。该形变带从吉仁台延伸到乔尔马以东，东西总长124km，南北最宽处约28km，地震断层断续展布97km，最大垂直错距为15m，水平位移为4m。

英文摘要：

Through using methods of several field inspecting and topographical deformation measuring, we studied plane distribution, activity and subsection characteristic of the fault of Nileke earthquake in 1812. And discussed difference of seismic slacktip structure, earthquake fault and gravity slide. And analyzed the latency relation between linearity coast back wall and earthquake fault. Based on accurate division with seismic fault and coast back wall, the maximal displacement is confirmed. The results show that the total length of the deformation zone in EW from Jiren sta- tion to east of Mayibulake is 124 km, the width of the deformation zone in NS is about 28 km, its length of distributing of the intermittently fault is 97 km, the maximal uprightness dislocation of the earthquake fault is 15 m, and the level displacement is 4 m.
