摘要
介绍了福建省流动地磁野外观测及资料的处理情况。利用 1990年以来的流磁资料 ,采用常规差值法和差值滑动滤波方法 ,分析了 90年代发生在我省及邻近海域的地震与地磁异常变化的关系。结果表明 ,震前存在着地磁异常的变化信息 ,反映出地磁异常的复杂性。
The mobile geomagnetic field observation and the data processing in Fujian area are presented. Using the data observed since 1990, the relationship between the earthquakes which occurred in the nineties in Fujian and offshore area,and geomagnetic anomalous variation by the methods of difference and smoothing mean are studied. The results show that there is the geomagnetic anomalous variation before earthquakes and the variation is complex.
