a Relationship between P-wave attenuation values obtained in this study and P-wave velocity perturbations (Nakajima and Hasegawa 2007) at a depth of 25 km for each grid node located beneath the NKTZ (purple shading in Fig. 1). The number of grid nodes shown is 109. The cross-correlation coefficient for the two data sets is −0.47. Colors represent the distance along the NKTZ calculated from point A in line A–B (Fig. 4). b Relationship between P-wave attenuation values obtained in this study and P-wave velocity perturbations that are averaged at every 20 km along line A–B. Bars denote 1-sigma uncertainties
