【摘要】 在 1 98 9年大同 6.1级、1 990年大海坨山 5.0级及 1 998年张北 6.2级等地震前 ,平谷地震台的地电阻率都出现了不同程度的异常。文中对每个地震地电阻率异常做了分析 ,并根据台站的地质构造情况作进一步探讨更多还原

【Abstract】 Before Datong earthquake with magnitude 6.1 in 1989, Dahaituo Mountain earthquake with magnitude 5.0 in 1990 and Zhangbei earthquake with magnitude 6.2 in 1998, earth resistivity anomaly appeared at Pinggu Seismic Station to different degrees. This paper introduced the change of earth resistivity anomaly for every earthquake and conducted further analysis based on the geological tectonics around the seismic station.更多还原
