The final velocity model. The numerals are P-wave velocities in km/s. The interval of the velocity contours is 0.4 km/s. The velocities are also color-coded. A blank region indicates no ray coverage. The vertical axis is the depth from the sea level. The horizontal axis is the distance from the southwestern end of the survey line. Triangles indicate the positions of OBSs. Interfaces between the plates are clearly recognized. The red arrow indicates the northeastern limit of the Philippine Sea plate according to Uchida et al. (2009).
