摘要
德令哈地应力自1997年投入观测以来,在青海及其邻近地区发生了4次Ms≥5.9级地震,在这4次地震前德令哈地应力观测资料显示出明显的短临异常。本文使用形态分析和斜率法对这几次异常进行了分析,对其短临异常特征结合地震的破裂类型进行了初步总结。
Four earthquakes with Ms ≥ 5.9 occurred in Qinghai and its neighboring area since 1997. The ground stress data recorded by Delingha station are obvious abnormal before those events, and their characteristics and fracture types are analyzed by the methods of shape and slope analysis.
