江苏高邮地震台地磁变化与地震关系的初探

Preliminary Study on Relation between Geomagnetic Field Variation of Gaoyou Seismological Station and Earthquake Occurrence

分析了江苏高邮地磁台1980年至2002年地磁垂直分量日变幅逐日比值的高值异常与江苏及邻区ML5.0以上地震之间的关系,发现它们之间有良好的对应关系,通过分析地磁垂直分量谐波幅度的逐日比,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。

Through analyzing the relation between the high value anomalies of ratio of daily amplitude variation,from 1980 to 2002,of vertical geomagnetic component of Gaoyou Seismological Station of Jiangsu and earthquakes occurred in Jiangsu and its adjacent area, it is found that those anomalies correspond earthquakes quite well. Through analyzing the ratio of daily harmonic amplitude of vertical geomagnetic component, the parameters, suitable for Gaoyou geomagnetic station, for earthquake prediction are proposed and the assessment for their predicting ability is made. 
