| 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. |
