Depth slices concerning the seismic wave speed model. a V s and b V p models. The left, center, and right panels show the wave speed of m 00, the wave speed of m 16, and the difference between the wave speeds of m 00 and m 16. Open squares and red triangles represent F-net stations and volcanoes, respectively. In (a), active faults and the MTL are shown as black lines and a broken line, respectively
