Abstract

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
