俯冲大洋板块与上覆岩石圈之间的相互作用造成板间的逆冲断层地震。全球地震图显示,这些地震的分布与俯冲边界非常一致。当考虑地震能量释放,发现这里释放出全球地震总能量的90%以上。通过区分马里亚纳型和智利型弧,即区分弧后构造应力是张性还是压性,对这种引人注目的情况作了进一步的分析。本世纪最大的地震,似乎无一出现在马里亚纳型边界。因此上田等断定,大洋板片与上覆板块的相互作用,在上述两种极端情况之间有着明显的变化。马里亚纳的情况是板片相对自由地沉入地幔。然而,在智利板片与上覆板块接触处遇到强大的力学阻抗。自然,这种耦合作用可以随板块形状及板块运动的变化而有所不同。当各种海底构造抵达俯冲带,耦合作用也可能发生变化。并且,这些观察成果表明,
The interaction between the subducting oceanic plate and the overlying lithosphere resulted in thrust faults between the plates. Global seismograms show that the distribution of these earthquakes is very much in line with the subduction boundary. When considering the release of seismic energy, it is found that more than 90% of the total global seismic energy is released here. This compelling case is further analyzed by distinguishing the Mariana and Chilean arcs by distinguishing whether the post-arc tectonic stress is tensile or compressive. It seems that none of the largest earthquakes of this century were on the Mariana boundary. Therefore, Ueda et al. Concluded that the interaction between the ocean plate and the overlying plate has obvious changes between the two extreme cases. The case of Mariana is the relatively free fall of the plates into the mantle. However, there is a strong mechanical resistance at the contact of the Chilean plate with the overlying plate. Naturally, this coupling can vary with the shape of the plate and the movement of the plate. Coupling effects may change as various seafloor structures reach the subduction zone. And, these observations show that,
