Seismic profiles along line SJ1901: a reflection profile obtained by RTM from airgun-OBS data in this study and b velocity model obtained by traveltime tomography (after No et al. 2020). c 3D view of compiled seismic profiles of RTM images overlaid by tomography velocities along the two crossed lines with bathymetry. The crust varies from the thick oceanic crust beneath the Yamato Basin to the continental crust beneath Honshu Island, which was classified by Sato et al. (2014, 2020). The yellow dots indicate OBS locations, and the red circles denote the probable Moho reflections
