Calculated thermal state of the upper surface of Vanuatu. (a) The calculated temperature distribution. The white dashed lines represent the isotherm contours of 300 °C and 700 °C. (b) The calculated temperature gradient distribution. The white dashed lines represent the depth contours of 30 km, 50 km, 70 km, and 90 km. In both figure panels, the solid red lines show the plate boundary. The red cones indicate active arc volcanoes77. The colored spheres indicate the intraslab seismic events from January 2000 through December 2010 (IRIS)74, with the color indicating the earthquake magnitude and the size mimicking the rupture dimension.
