摘要
安徽省利辛县张村镇 1 999 1 2 3 0发生M4 1地震 ,震前数日省流磁测量组在皖北进行了 1 999年第 4期流动地磁测量。运用Sδf方法分析此期流磁资料 ,可见明显异常。震后 ,异常恢复。分析认为 :Sδf方法在运用流磁资料作短期地震预报方面具有一定实用性。
An earthquake of M =4 1 occurred on Dec 30,1999 in the Town of Zhangcun,Lixin County,Anhui Province The fourth-term measurement of the mobile geomagnetic survey of 1999 was made by the provincial mobile geomagnetic surveying team in the northern part of the province several days before the earthquake Obvious anomalies appeared in the analysis results of this term mobile geomagnetic data using S δf method The anomalies disappeared after the earthquake The analysis has shown that the S δf method has some practical value in the short-term earthquake prediction using the mobile geomagnetic data
