Figure 3
Vertical sections of P-wave velocity anomalies from surface to the core–mantle boundary along the lines AB and CD in Fig. 1. White dots represent hypocenters54 within a band that is 50 km wide on both sides of the section plane. Tics are added on the upper frame of each cross section at every 5° from the left hand side. H–H3 and L1 indicate the same anomalous regions in Fig. 2.
