台湾、寻乌地震前泉州四至村井水化学异常分析

THE ANALYSIS ABOUT CHEMICAL ABNOMALITY OF WELL WATER IN QUANZHOU BEFORE THE EARTHQUAKES OF TAIWAN AND XINWU

分析了泉州四至村井1984年至1987年地下水化学组份的变化特点后,发现Cl^-、Ca^(++)Mg^(++)、水电导率在寻乌5.5级地震前,Rn、PH值在台湾7.6级地震前均有明显的异常。认为这些异常可能是地震前兆异常。

In this paper, the characteristics has been analysed in the variations of chemical components in groundwater at Sizhicun well from 1984 to 1987. It was found that the anomalies of CL, Ca, Mg, electrical conductivity of water before Xunwu earthquake (M=5.5) and Rn, Ph befo re Taiwan earthquake (M=7.6) are marked, these anomalies are considered to be the precursor anomaly of earthquake.
