摘要
应用经典方法对山西河津4.8级地震前周边形变台站测项资料的分析发现,大部分测项震前出现中、短临前兆异常,异常测项占统计测项的78%。
By use of the classical method through the analysis of the observations before the Hejin 4.8 earthquake at the deformation stations around the epicenter,we discovered that there occured many medium-short-impending anomalies,they constitued the majority in the most of monitoring terms.
