摘要
应用地磁空间相关方法对华北地区1996年1月至1998年1月地磁核旋定点(北京时21h)观测数据的分析研究表明,1998年1月10日张北MS6.2地震和1996年5月3日内蒙古包头MS6.4地震前存在地磁空间相关低值异常。
The fixed point geomagnetic data observed by the nuclear precession magnetometer from January 1996 to January 1998 are analyzed by the method of geomagnetic spatial correlation.The result shows that there exist low value abnormalities of geomagnetic spatial correlation before Zhangbei M S 6 2 earthquake in Hebei Province on January 10,1998 and in Baotou M S 6 4 quake in the Inner Mongolia Autonomous Region on May 3,1996.
