P-wave structure along the depth slice. a At 15 km depth. The green line is the iso-value contour of Vp = 6.5 km/s in our model. Black lines show the spatial extent of Vp > 6.5 km/s along the Y direction (− 30 ≤ X ≤ 40 km). The blue line shows the high velocity zone estimated by Arnulf et al. (2022). b At 30 km depth. The green line is the iso-value contour of Vp = 7.0 km/s in our model. The red solid and dotted lines show the Vp contours of 6.5 km/s and 7.0 km/s 15 km deeper than slab Moho discontinuity estimated by Arnulf et al. (2022), respectively
