对1989年以来华北北部6级左右地震前山西形变映震识别的思考

Thinking about Reflecting Earthquake Recognition for Deformation Measurement in Shanxi before about M6 0Earthquakes of Northern Part of North China since 1989

从山西省形变观测的基础资料入手，回顾了各形变观测台（站）在山西大同—阳高６．１级地震、内蒙古自治区包头６．４级和河北张北６．２级３次地震前后的异常追踪落实过程，并对其进行了认真的思考。给出了思考之后的启示。

Starting out the deformation measurement data in Shanxi , the processes of the anomaly tracing and verification for the deformation measurement stations before and after the M6 1 Datong-Yanggao earthquake in Shanxi, the M6 4 Baotou earthquake in Inner Mongolia and the M6 2 Zhangbei earthquake in Hebei were reviewed , and the careful thinking was made Some suggestions were proposed
