Fig. 13From: Upper mantle structure beneath the Society hotspot and surrounding region using broadband data from ocean floor and islandsResults of synthetic tests for LAB depths. Synthetic models have 4 % slow velocities than the initial model and LAB depth at a 80 km, b 70 km, c 60 km, and d 50 km. Lithosphere is 1 % slow velocities than the initial model. Lines are as in Fig. 6. Red arrows show the estimated LAB depths from the maximum of the negative shear wave velocity gradientBack to article page
