Seafloor age and heat flow in Vanuatu. The yellow line indicates the study region. The yellow arrows show the convergence velocity. The red barbs on the black solid line mark the convergent plate boundary. The red triangles with white outlines indicate volcanoes77. The solid circles represent observations from the global heat flow database, with the circle color corresponding to the “Heat flow” color scale in the bottom right corner of the figure36. The seafloor age, with the color corresponding to the “Seafloor age” color scale in the bottom left corner of the figure, was obtained from EarthByte33. The gold stars indicate M ≥ 7.5 earthquakes that have occurred in the past century.
