摘　　要：以霍山“震情窗”地区流动地磁测线的 S值变化 ,预测霍山“震情窗”相关地区—华东地区中强地震。研究结果表明 :“震情窗”地区流动地磁测线的 S值异常与距离霍山“震情窗”R<5 0 0based on the variation of S value from mobile geomagnetic survey in Huoshan'earthquake window'area,the medium earthquakes in Southeast China are predicted.The results show that the anomalies of S value in the area is correlated obviously with the earthquakes in Southeast China area within the range of 500km from Huoshan.
