摘要
The earthquake-generated tsunami (especially the big earthquake- generated tsunami) is mainly induced by the secondary and huge volumetric submarine landslide and collapse caused by ocean-bottom earthquake, rather than the submarine coseismic dislocation and deformation. If there exist unstable submarine landslide and collapse bodies nearby the epicenter, earthquake, regardless of the size, the focal depth, or the source type (namely, dip-slip or strike-slip) of it, will induce submarine landslide and collapse, and then generate tsunami. Otherwise, it will not generate tsunami even with big magnitude or dip-slip.
