壳内强震与地震地幔柱的关系
Seisman
全球1963年以来M≥7.5、h≤50km的壳内强震目录见表1,共计126个。图1是全球壳内强震的空间分布(红色空心圆圈),为了便于对比,图2展示了全球地震地幔柱的空间分布图像。
对比图1和图2,126个壳内强震中,只有2-3个地震姑且与地震地幔柱无关,尚待进一步研究。98%以上的壳内强震均受到已定义的25个地震地幔柱严格控制,而且其中有7个已定义的地震地幔柱没有7.5级以上的壳内强震活动。
这个结果也是极为令人兴奋的,与朋友们分享吧。
附带说明:在西半球的南极洲,西经45°、南纬60°之处,有现代火山活动,也有7.5级以上的壳内强震活动,似乎可以定义为一个次级的地震地幔柱,即F4南极西地震地幔柱。
