怀4井汞量异常与地震的关系
THE RELATIONSHIP BETWEEN MERCURY ANOMALIES IN HUAILAI NO.4 WELL AND EARTHQUAKES
【摘要】 首先介绍了怀来4 井地质构造情况,然后根据怀来4 井1989—1998 年水汞观测资料,分析了4 次中强地震前汞量异常与地震的关系。结果显示,怀来4 井汞量异常与地震前的地震活动异常有较好的对应关系。
【Abstract】 In this paper,the geological structure of Huailai No.4 well has been introduced first,then the relationship between the mercury anomalies and earthquakes before 4 moderately strong earthquakes has been analyzed according to the mercury observtion data in Huailai No.4 well from 1989 1998.The result shows that the mercury anomalies showed a relatively good corresponding relation to the seismic activity anomalies before earthquakes.
