武威台地电阻率异常变化与映震效果讨论

Discussion on the Resistivity Anomaly Characteristics of Wuwei Station and Its Reflecting Earthquake Ability

摘要:

首先对武威地电台的台址、观测仪器、测项布设及观测环境等进行了简述。基于该台1983年以来的地电阻率观测结果,对甘肃及邻区(部分)MS≥5.0以上地震的临震异常特征与地质构造、电性结构、映震效果进行剖析,可为祁连山中西段地震前的预测预报提供较为可靠的地震三要素的依据。

Abstract:

The basic matters of Wuwei geo-resistivity station including its location,observation instrument, pole arrangement and observation environment are introduced first. Based on the observation data of geo-resistivity from 1983, the anomaly characteristics before Ms≥5.0 earthquake events in Gansu province and adjacent regions with their geotectonics, electricity property condition and reflecting earthquake abilities are analyzed. The result could afford relatively credible criterion to the three essentials of earthquake prediction in the middle and west Qilian Mountain.
