| Abstract: | Through analysis on deep well geoelectricity data of Linyi station which is 23 km away from the epicentre of the Cangshan M S 5.2 earthquake,it is shown that before the earthquake,the background tendency anomalies of the deep well resistivity and natural geoelectric potential appeared synchronously with the seismicity anomaly for 5 years.The descending tendency anomaly of deep well resistivity occurred six months before the earthquake.The natural geoelectric potential and resistivity reduced rapidly 24 days before the earthquake,and then rose again abruptly after the earthquake. |
