| 摘 要： | 应用曲线拟合和去趋势提取完整年变周期的方法,结合海安地震台台站周围震中距小于300km的MS4以上地震,分析了海安地震台2008~2012年地电阻率观测资料。结果表明,海安地震台地电阻率在中强地震发生前均出现不同形式的破年变变化,并且地震均发生在破年变变化恢复后一个月内,此结论可为今后江苏及邻近地区中强地震提供中短期预报依据,尤其是发震时间的判断。同时,这一震兆异常也为研究同一构造上的地电阻率异常与地震的关系提供参考。

| Abstract: | This paper analyzed earth-resistivity data from 2008 - 2012 using fitting method and de- trended annual variation according to earthquake with Ms ≥4.0 around Hal ＇an seismic station within 300 km. The results showed： the earth-resistivity of Hai＇an seismic station broke annual variation a month before moderate earthquake which provided reliable earthquake prediction criteria for Jiangsu and its adjacent region, especially for origin time. It also provided reference for study relationship between earthquake and earth-resistivity in the same fault. |
