Fig. 11

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
