摘要
近年来在我国井网中发现某些强震之前井水位记震特性的异常现象。本文根据理论分析、试验研究与井网中统计结果提出水震波异常与区域应力状态的变化之间可能存在着一定关系,然后广泛收集了华北地区15口井水位1985—1991年间的水震波资料并系统分析了1989年10月19日大同—阳高M_s6.1地震前后井水位记震特性的变化,确认强震前存在着水震波异常。
Some anomalous phenomena of response of water level to seismic wave before an earthquake are recently discorved in the Chinese well network. On the basis of some results of theoretical analysis, test stuty and statistics of the well network-, it is put forward that there are probably some relations between the anomalies of seismic wave of water level and the change of regional stress state. The data of seismic wave of water level of 15 wells in North China during 1985-1991 are extensively collected, and the change of recording capacity before and after Datung-Yanggao earthquake, Ma 6.1, 19, October, 1989, is systematically analysed and the'anomalies are verified.
