摘要
本文对澜沧-耿马7.6级、巴塘6.7、5.8级、小金6.6级强震前的地磁异常作了分析研究。震前地球基本磁场出现了趋势性异常。地磁垂直分量日变“低点位移”、“幅相法”和日变形态分别出现了完整或较完整的短临异常。震前我们曾作了不同程度的预测,并取得了一定实效。
Geomagnetic anomalies before strong earthquakes of Lancang-Gengma M 7.6, Batang M 6.7, 5.8 and Xiaojin M 6.6 have been analyzed and studied in this paper. There existed tendency anomalies in the basic geomagnetic field before these earthquakes. There appeared complete or relatively camplete short and impending anomalies in the '''low-point displacement' of geomagnetic vertical component, 'amplitude-phase method' and the shape of diurnal variations. Prior to these strong shocks, we made prediction to varying degrees and achieved certain actual effects.
