摘要
采用不同的方法研究了河北万全水位异常与区域中强地震活动的关系 ,发现万全深井水位在 1 989年 1 0月 1 8日山西大同—阳高 6.1级地震前及 1 998年 1月 1 0日河北张北 6.2级地震前有趋势性变化 ,水位有大于50 mm的瞬时突升突降的变化。指出 。
Based on the study of the relation between abnormal changes in Water level of the deep well of Wanquan, Hebei and medium strong earthquakes occurred within the region, the trending changes are found. The water level went up and down suddenly with magnitude larger than 50 mm before Datong Yanggao earthquake of M=6.1of Oct.18,1989 and Zhangbei earthquake of M=6.2 of Jan.10,1998.The conclusion is that the morphological and sudden changes in water level of the deep well of Wanquan can be taken as one of the indexes for judging earthquake situation of the joint area of Shanxi, Hebei and Inner Mongolia provinces.
