A seismic refraction study using OBSH and explosives was carried out in the Bonin Trough. The P-wave velocity model along the trough axis consists of 4 layers; the velocities, Vp, of these layers are from top to bottom 2.0, 3.6, 6.3 and 7.8 km s-1 respectively. The thickness of the crust is 13 km at the northern part of the trough and becomes thicker toward the south. The negative free-air anomaly pattern in the trough can be explained by thickening of the crust.
