太阳活动周磁暴与亚洲M_S 7.0以上地震活动关系

Relationship between intense geomagnetic storm in solar cycle and Asian M_S ≥ 7.0 earthquakes

将1996—2015年太阳黑子数、强磁暴和M_S≥7.0亚洲浅源地震,按Dst指数大小对磁暴进行分类和统计,按震级大小对地震进行分类统计,结果发现,在1996—2015年太阳活动周下降年易发生大磁暴,且M_S≥7.0地震年发生率明显高于太阳活动周上升年、极大年和极小年。

We collected data from 1996 to 2015 about sunspot number, intense geomagnetic storm and strong Asian earthquake（MS≥ 7.0）, and classifiedgeomagnetic storm by Dst, Asian earthquake by MS. Data analysis found that the intense geomagnetic storm number in solar declining years is larger, earthquake occurrence rate is larger than that in ascending,solar maximum and minimum year.
