摘要
应用加卸载响应比法、日变幅逐日比法及空间相关分析法,分析研究了江苏高邮地磁台1992年至1997年地磁垂直分量的观测资料,结果发现,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。
Through analyzing observed data, from 1992 to 1997,of vertical component of Gaoyou Seismological Station of Jiangsu , by using the response ratio as loading and unloading,ratio of daily amplitude variation and spatial correlation analysis, it is found that there are obvious geomagnetic anomalies at Gaoyou Seismological Station of Jiangsu before medium-strong earthquakes.Some parameters for earthquake analysis and prediction, suitable for Gaoyou Seismological station, are proposed.
