绥化台地电阻率异常与龙镇震群

分析研究绥化地电台近十年地电观测资料,认为1986年发生在德都龙镇的中强震群,绥化台地电阻率存在趋势异常,并明显呈现短临异常前兆特征。同时,指出绥化台地电阻率趋势异常的继续存在及其周围250km范围内仍有发生中强地震的可能。

EARTH-RESISTIVITY ANOMALY OF SUIHUA GEOELECTRICAL OBSERVATORY AND EARTHQUAKE SWARMS IN LONG ZHEN

On the basis of analyzing and researching geoelectrical observations at Suihua geoelectri- cal observatory in recent ten years, the author holds that earth-resistvity of the station ap- peared to exist tendegtious and short-term or impending anomalies before the moderate earthquake swarms occurred in Longzhen, Dedu county, 1986. Meanwhile, the author also points out that tendentious anomaly of Suihua observatory is going on, and there is still the probability of moderate earthquake occurred in a rangeover 250km.
