摘要: 在1989年大同6.1级、1990年大海坨山5.0级及1998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。

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 resistivi tyanomaly appeared at Pinggu Seismic Station to different degrees. This paper int roduced the change of earth resistivi ty anomaly for everyearthquake and conducted further analysis based on the geological tectonics around the seismic station.

Key words: Earth resistivity, Precursor anomaly, Capital circle region, Pinggu seismic station
