摘要
对大同—阳高、忻州3次中强地震的地磁场总强度△F异常变化的时、空、强进行了总结。认为△F异常变化的空间展布与主干断裂有关,提出磁异常有时间长、连续性好、空间分布广、强度由弱到强的特点。
The time, space and intensity of the abnormal change of the geomagnetic total intensity (△F)of 3 moder-ate earthquakes in Datong Yanggao and Xinzhou have been summarized in this paper.The author suggestedthat the spatial distribution of the △F abnormal change is relative to the main trunk fracture,and the geomag-netic anomaly is characterized by long duration time,wide spatial distribution and intensity from low to hig.
