Fig. 5

Relocated hypocenters in the present study plotted on the horizontal cross-sections of P and S wave velocities estimated by Kita et al. (2012). Green dots indicate the hypocenters of aftershocks within 2.5 km in the depth direction, and the white stars in i and l indicate the mainshock. The P wave velocities are shown at depths of 10, 15, 20, 25, 30, and 25 km in ac and gi, respectively. The S wave velocities at these depths are shown in df and jl. Note that the color scales for af are different from those for gl. Contours indicate P and S wave velocity values at intervals of 0.6 and 0.4 km/s, respectively. Green and green dashed ellipses indicate the location of intrusion of the high-velocity materials. Gray lines indicate the locations of thrust faults. The black area and thick black lines indicate the locations of the Hidaka metamorphic belt and the coast line, respectively. White-shaded areas indicate portions of DWS < 500
