Tonga-Fiji events. (a) Locations of the five events, FEV2, FEV10, FEV12, KEV1, and KEV6. (b) CMB piercing points for S2KS and S3KS for the four events. Triangles and circles show the core entry points of S2KS and S3KS for each event, respectively. The large black circles are drawn to mark a reference point referred as below. (c) The V _s anomalies in the D ^′′ beneath Vanuatu around the CMB piercing points of the Fiji-Tonga data set for the five tomography models: SAW24B16 (Megnin and Romanowicz 2000), S362ANI (Kustowski et al. 2008), HMSL (Houser et al. 2008), SH18CE (Takeuchi 2007), and S40RTS (Ritsema et al. 2011). The V _s anomalies are shown with color code and contours. The large black circles show the reference point. Bottom right panel shows a model with an extreme and sharp-edged anomaly, like LLSVP. The piercing points of S2KS and S3KS for three of the five events are shown in this panel only
