Vp models, checkerboard test results, and ray coverage. (a) Vp models across the northwestern Oki-Daito Ridge in the broad sense for lines OKr4 (top), ODr9 (middle), and ODr1 (bottom). The double-headed arrow indicates a middle crust with Vp of approximately 6.3 to 6.8 km/s for each profile. The positions of the seismic profiles are indicated by blue dashed lines in the lower right corner in Figure 8a. (b) Checkerboard test results and ray coverage for Vp models across the northwestern Oki-Daito Ridge in the broad sense for lines OKr4 (top), ODr9 (middle), and ODr1 (bottom) that are shown in (a).
