Tomographic inversion settings. a Crosses, blue diamonds, and colored circles reflect the horizontal distribution of grid nodes for the velocity model, stations, and initial hypocenters, respectively. b Initial P-wave velocity model along trough-normal profile at Y = 0, and along trough-parallel profile at X = 0 km. Initial hypocenters are shown as black dots. Red line is the plate boundary of Nakanishi et al. (2018). Thin black lines are P-wave velocity contours between 6 and 8 km/s (0.5 km/s increment). Vertical exaggeration = ×2.0
