摘　　要：通过对山西数字化地震前兆观测资料的分析,发现日本本州东海海域9.0级地震前后,山西地区应变仪、钻孔倾斜仪出现了不同程度的形变异常。对这些异常特征进行对比分析,为今后地震预测提供依据。By analyzing data of Shanxi digital seismic precursory observation, it is found that deformation anomalies appeared in different degrees for strain gauge and tihmeter in borehole in Shanxi before and after the Japan East Sea M9.0 earthquake. These anomalies are analyzed, which can be taken as the basis for future earthquake prediction.
