| Abstract: | 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 |
