摘要
本文介绍了共和地震后所测到的源兆型大地形变异常,讨论了异常出现的时间、空间及异常与区域构造应力场的关系。指出形变测量手段有能力捕捉到此种地震前兆信息。
The anomaly of precursor deformation obtained in the focal area is described in this paper. The time and space of anomaly and the relations between the anomaly and the regional structure stress field are discussed . It is indicated that the precursor information of this kind of earthquake can be catched by means of the deformation measurement like the levelling.
