| Abstract: | 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. |
