    大地震前震中上空电离层全电子含量异常研究

    A Study of Pre-earthquake Ionosphere TEC Anomalies Upper Epicenter

      摘要
    • 摘要: 采用IGS(International GPS Service)网站提供的电离层垂直全电子含量(vertical total elearon content,记为VTEC),分析研究了1998—2006年发生在中国大陆地区的30个Ms≥6.0的地震.采用统计处理的方法,讨论了地震前后15d内电离层全电子含量的变化,分别对震中上空电离层全部TEC资料进行了分析.

       

      Abstract: In this paper we analyzed 30 Ms≥6.0 earthquakes which occurred in the mainland of China from May 1998 to December 2006 by the vertical total electron content(VTEC)supplied by IGS(International GPS Service)web.Utilizing the statistical methods,we discussed the variations of the ionospheric TEC occurred 15 days beforg and after earthquakes.Selectively,we studies all ionosphereic TEC data above the epicenter and the data excluding magnetic storm.
