| 摘 要： | 分析了首都圈及邻近地区跨断层基线测量资料，研究了唐山、大同及张北地震前后断层水平异常活动特征。结果表明，震前在震中外围存在显的断层水平异常活动，监测断层水平活动是地震预测的有效手段；同一测点震前断层水平异常活动具有相似性特征；唐山地震前在震中附近一定范围内出现的断层水平异常活动，具有断层预位移性质。

| Abstract: | In this paper, the authors have analyzed the data of base line measurement across faults and studied the characteristics of fault horizontal anomalous movement before and after Tangshan, Datong and Zhangbei earthquakes. The results show that there is remarkable horizontal anomalous movement before earthquakes in epicentral region and its periphery. Monitoring horizontal movement of fault is an efficient approach for earthquake prediction. The horizontal anomalous movement of fault has similar characteristics at the same station before earthquakes. The horizontal anomalous movement of fault has the advanced movement quality before Tangshan earthquake around its epicenter. |
