a S-wave velocity and b attenuation models including the high-attenuation zone in the mantle wedge (HMW) along cross-section D (Fig. 1). b Values in white boxes are the \({Q}_{\mathrm{S}}\) values at 8–16 Hz. The three black lines represent the structural boundaries of the Conrad and Moho discontinuities (Katusmata 2010), and the upper boundary of the Pacific slab (Nakajima et al. 2009)
