| 摘 要： | 将形变速率累加法应用于山西地区4个定点水准观测资料分析,研究计算结果与本区域及邻区中、强地震的对应关系,发现震前一些连续的异常“孤立”点,经过积分放大后,异常信息的提取更直观、突出,显示出较好的映震效果;该方法对于跨断层资料的异常识别,具有一定的参考意义。

| Abstract: | The method of accumulation deformation rate was used to calculate data from four fixed-point observation sites in Shanxi Province, and the relationship between the measurement results and moderate and strong earthquakes in this area and adjacent areas were analyzed, and some continuous abnormal outliers were identified before the earthquake. The anomaly information extraction was more intuitive and prominent, showing a strong earthquake-reflective effect. This approach has certain reference significance for the anomaly identification of cross-fault data in Shanxi. |
