Geomagnetic Day by Day Ratio and Its Relationship with Strong Earthquakes in Xinjiang and Its Adjacent Areas

  • 摘要: 利用2009年1月1日至2019年12月31日新疆及周边区域12个地磁台站的地磁垂直分量日变幅数据,计算其日变幅逐日比,进而分析新疆及周边地区逐日比异常特征,研究其与磁暴和强震的关系.结果表明:强地震多发生在逐日比异常出现后半年,其中等待时间最短为20天,等待时间最长为220天,震中多位于异常集中区域或异常分界线及附近区域;新疆及周边地区逐日比异常报对率为78%,异常虚报率为22%,研究时间段内没有出现漏报现象,说明新疆及周边地区强地震与逐日比高值之间存在一定的相关性;若异常日前后未发生强磁暴或其Dst指数小于异常第二日,则异常可能性较大.本研究增强了地磁垂直分量逐日比异常判据的可靠性,其结果可以为新疆强震活跃期的判定及地震预报提供研究参考依据.
