江苏井网水位动态的远震效应研究

STUDY ON THE TELESEISMIC EFFECT OF WATER LEVEL VARIATIONS OBSERVED IN THE WELL-NETWORK OF JIANGSU PROVINCE

本文对江苏地下水动态观测网记录到远震前的井水位变化图象特征及其与地震强度、时间、方位和井孔所处断裂带活动强度等关系进行了系统的分析研究.指出利用井网记录的水位异常信息,有可能对位于江苏省东南方向的台湾及其附近地区地震作出一定程度的预报.并对映震井孔的条件,远震效应的机理进行了探讨.

This paper has studied systematically the water level changes prior to teleseism observed in the groundwater well-network of Jiangsu and its relation to earthquake magnitude, time, direction and the fault activity on which the well is located. It is concluded that the water lerer anormaly recorded in the well-network can be used to predict to some extent the earthquake occurring in Taiwan or its nearby regions to the southeast of Jiangsu. Furthermore, the conditions of well in which anomalies were recorded and mechanism of teleseismic effect are discussed.
