【摘要】 介绍陕西省周至地电阻率台址及地电观测环境和观测系统运行情况,分析汶川大震及强余震前地电阻率出现的短临异常变化;记录到显著的地电阻率下降异常、地电阻率日均值均方差增大和差分能量增大的显著异常,认为周至地电台具有良好的监测地震能力。更多还原

【Abstract】 In this paper,the location and observation environment of geoelectrical resistivity observation in Zhouzhi Seismic Station and its short-term precursory anomalies before Wenchuan earthquake are introduced.From the recording,we got a remarkable decreasing anomaly of geoelectrical resistivity observation,and increasing anomalies of the first-order differential number and energy of geoelectrical resistivity daily value in Zhouzhi Seismic Station.So we think this station have a good ability to monitor earthquake.更多还原
