摘要
《2005.0中国地磁图》的编制完成,为地震地磁监测引出一套新的思路。江西九江-瑞昌M_s 5.7地震发生后,通过对震区一定范围内地磁分量跟踪测量,在《2005.0中国地磁图》基础上,局部修正了该区域2005.0地磁基本场分量的曲面样条模型。该结果很好的表现了该区域地磁基本场分量空间分布形态的变化,为地震预报提供了数据基础。同时,该方法在安徽地区前兆异常核实中也得到了很好的应用。
The completion of“Map of the Geomagnetic in China 2005.0”brings us a new train of thoughts for the earthquake monitoring and forecast.Through the survey of geomagnetic components in some certain areas after Jiujiang-Ruichang Ms 5.7 earthquake,and make out the correction surface spline model of geomagnetic components in this area base on“Map of the Geomagnetic in China 2005.0”.The results describe the change of space distribution of geomagnetic components in this area very well,and offer the data basic for earthquake fore- cast.At the same time,this method is applied for checking precursor anomalies in Anhui Province successfully.
