地震地电方法在天祝—景泰6.2级地震前的预测预报

本文通过对天祝—景泰6.2级地震监测预报工作全过程的研究,展示了地电方法监测预报地震的新进展。另外,对如何运用地电场的分布变化规律及地电阻率异常时间、幅度的特征进行监测预报作了探讨。

MONITORING AND PREDICTING TIANZHU-JINGTAI Ms 6.2 EARTHQUAKE BY GEOELECTRIC METHOD

This paper reveals that the earth resistivity has obvious tendency and short-term anomaly before the earthquake review of the whole process of monitoring and predicting Tianzhu-Jing-tai Ms6.2 earthquake. These anomalous features were fully used in the monitoring and predicting work and achieved more obvious prediction effect. Combined many years' experiences engaged in earthquake prediction, authors here discussed the related problems, such as new progress by using earth resistivity observation in medium-short-term earthquake prediction, spatial distribution regularity of geoelectric field, anomalous time and amplitude of geoelectricity and earthquake monitoring and prediction, etc.
