According to dissecting depth of the zone of faults, the two zones of faults with upwelling of magma were transcrust (crust-upper mantle zone of faults).

根据断裂带切割深度，认定这两个断裂带均为超壳断裂，且都有岩浆上涌。

But geophysicists had thought that great subduction-zone earthquakes happened only where younger oceanic crust scrapes its way into the mantle.

但是在此之前，地球物理学者们认为，这种俯冲带大地震仅仅在年轻的海洋地壳挤入地幔处才可能发生。

A sharp temperature increase across the mid-mantle transition zone inhibits a simple downward-extrapolation from the near surface data.

中地幔过渡带有一个温度突然增加，因此不能根据近地表数据向下做简单的外推。
