高邮地磁台加卸载响应比与江苏及邻近地区的地震预测

Loading/unloading response ratio at Gaoyou Geomagnetic Station and earthquake forecasting in Jiangsu and neighbouring area

研究分析了高邮地磁台1980～2001年观测资料的加卸载响应比异常与江苏及邻近地区ML5.0以上地震之间的关系,提出了适用于高邮地磁台的地震分析预报参数,并对其内检预报效能进行了评价。

The relation between the anomalies of the loading/unloading response ratio and the earthquakes of magnitude ML≥50 in Jiangsu and neighbouring area is studied and analysed using the observational data recorded at the Gaoyou Geomagnetic Station in the period of 1980～2001. A parameter suitable for the earthquake prediction at Gaoyou Geomagnetic Station is suggested, and assessments are made of its prediction efficiency through a posterior prediction of earthquakes in this period.
