摘要
应用加卸载响应比法、日变幅逐日比法、空间相关分析法,研究分析了高邮地磁台1992～1997年地磁垂直分量观测资料发现,在中强地震前高邮台的地磁场存在明显的磁异常变化,提出了适用于高邮台的地震分析预报参数。
The geomagnetic data from 1992 to 1997 in Gaoyou Seismostation are analyzed with loading and unloading response ratio method, diurnal fluctuation comparison method and spatial correlation analysis method. Through analysis we found the geomagnetic field in Gaoyou area showed obvious anomalies before moderate and strong earthquakes. The prediction parameters that suit Gaoyou area are presented.
