(A) Along-strike seismic velocity structure of arc crust in the Izu-Bonin arc [Kodaira et al., 2007], showing finely-resolved variations in crustal thickness. (B) The composition of lavas erupted at Izu-Bonin frontal arc volcanoes correlates with (C) the thickness of the low-velocity (Vp=6.0-6.5) middle crust beneath each volcanic center.
