oceanic crust

Although many studies have been made to image the subducting Pacific slab in and around the Japan islands,details of the slab structure(such as the slab thickness,its seismic velocity,the subducting oceanic crust,as well as the depth variations of these factors)are still unclear.

尽管许多学者对日本列岛下的太平洋俯冲板块做了大量的研究,但板块内部的结构(比如板块厚度,板块内地震波速度随深度的变化以及洋壳的俯冲情况等)仍然不太清楚。
