摘要
2015年5月15日河源市东源县3.2级地震前,新丰江和平地电台地电阻率测值出现大幅度下降变化,对自然环境、观测系统,特别是场地环境进行分析,认为该地电阻率变化由测区内钻孔施工干扰所致,非地震前兆异常。
The greatly decline change of earth resistivity was observed at Xinfengjiang Geoelectric Station before Dongyuan MS 3.2 earthquake occurred on May 15,2015.By analyzing the observation system,natural and field environment during the resistivity anomaly,it is considered that the earth resistivity variations are not some earthquake precursor abnormalities,but resulting from the well drilling in measuring area.
