| 摘 要： | 使用琼中地磁台、肇庆地磁台2004—2006年的高精度数字化地磁观测资料,采用地磁短周期转换函数研究方法,系统地分析了琼中、肇庆地磁台周边地区在此期间的地磁异常和地震的对应关系。研究结果表明,在2004年9月17日阳江M_L 5.2地震前,琼中、肇庆地磁台的地磁短周期转换函数A、B,有比较明显的前兆异常。

| Abstract: | In this article, the geomagnetic data from the Qiongzhong and Zhaoqing geomagnetic ob- servatories during 2004 to 2006 are studied with a geomagnetic short period transfer function algorithm, in order to finding the relationship between the geomagnetic abnormal and seis- micity. The study shows that before the Yangjiang Earthquake on September 17, 2004, there is apparent abnormal precursor in geomagnetic short period transfer function A, B of Qiongzhong and Zhaoqing geomagnetic observatories. |
