Comparison of hypocenters (a, b) and focal mechanisms (c) of this study with a previous crustal model. Line BB′ shows the location of the refraction survey conducted by Nakahigashi et al. (2012), nearly perpendicular to the subduction direction of the PAC. Light gray dots show hypocenters based on the three-dimensional velocity model (Fig. 3b). Dark gray dots indicate the hypocenters of earthquakes within a 20-km-wide box on both sides of the BB′ profile
