地电阻率EW/NS比值变化与地震的关系

VARIATION OF EARTH RESISTIVITY RATIO IN EW AND NS DIRECTION AND ITS RELATION WITH EARTHQUAKES

摘要: 主要对河北省4个台站的两个方向(EW、NS)的电阻率比值进行了大量计算, 结果发现比值的变化能够很好地对应近年来河北省内发生的较大地震, 尤其是作为中长期地震异常有着很好的映震能力, 这对于预测和预报未来地震有着十分重要的意义。

Abstract: Through calculation to the ratio of earth resistivity in EW and NS direction that is recorded by 4 stations in Hebei Province, we found the ratio can reflect the earthquakes in Hebei Province in recent years perfectly, especially as medium and long term anomalies.It is significant to earthquake prediction.
