摘要
从山西测震学资料入手，在核实异常的基础上，总结了１９８９年以来华北北部３次６级左右地震前发异常，并对该方法的映震能力进行了初步检评，指出，这些地震前，山西北部存在着地震空区和条带异常，大山西大同－阳高老震区存在着临异常。
Based on the verification for the anomalies of seismological data in Shanxi, the anomalies before the 3 earthquakes with magnitude about M6.0 in the northern part of North China since 1989 were summarized ,and the reflecting earhquake ability of the method was preliminarily tested and evaluated.The paper suggested that there are the seismic gap and belt anomaly before the earthquakes in the northern part of Shanxi,and there are short-impending anomalies in the old seismic region of Dotong-Yanggao.
