海口ZK26井和ZK46井水位记录地震能力差异分析

The Differences of Recording Earthquake Capability by Water Level of ZK26 Well and ZK46 Well in Haikou

统计了海口ZK26井和ZK46井水位对2008年以来全球MS7.5以上地震的同震响应情况,得出所记录地震的次数及同震效应类型;并绘制两口井水位是否记录所统计地震的平面分布图(以震中距的对数为横坐标,震级为纵坐标),以此为基础得出两口井的水位记录地震能力曲线方程。根据所得的记震能力曲线方程,认为尽管ZK26井和ZK46井水位记震能力差异不大,但总体上ZK26井记震能力更优。

This paper collects the coseismic responds of water level of ZK26 well and ZK46 well in Haikou during the earthquakes with Ms≥7.5 in global from 2008, and obtains the frequency of the recorded earthquakes and the type of seismic respond. Then, based on drawing plane distribution map of whether the water level of these two wells can record the collected earthquakes, the paper produces the recording seismic capacity curve equation of these two water wells. Based on the recording seismic capacity curve equation, the author considers that although ZK26 well and ZK46 well have little difference in recording earthquake, the recording earthquake ability of ZK26 well is more excellent.
