Figure 4

North-south vertical cross section of seismic velocities. (a, b) Vp at the location of X = -20 km (a) and X = 10 km (b). Gray lines show the boundaries estimated from the receiver function. Black spots denote the relocated hypocenters within a horizontal range of 10 km from the cross section. Dotted line denotes the SSE fault. CMT solutions of the relocated hypocenters are after F-net, NIED. (c, d) Vp/Vs at the locations of X = -20 km (c) and X = 10 km (d). (e, g) The checkerboard resolution test of Vp at the locations of X = -20 km (e) and X = 10 km (g). (i, k) The checkerboard resolution test of Vp/Vs at the locations of X = -20 km (i) and X = 10 km (k). (f, h) The restoring resolution test of Vp at the locations of X = -20 km (f) and X = 10 km (h). (j, l) The restoring resolution test of Vp/Vs at the locations of X = -20 km (j) and X = 10 km (l). Dots in (e), (g), (i), and (k) show the grid points used in this study.
