Broad plumes rooted at the base of the Earth's mantle beneath major hotspots

A whole-mantle seismic imaging technique, combining accurate wavefield computations with information contained in whole seismic waveforms, is used to reveal the presence of broad conduits beneath many of Earth’s surface hotspots, supporting the idea…

Seismic evidence of effects of water on melt transport in the Lau back-arc mantle

Tomographically derived seismic velocities are used to infer the distribution of partial melt below the Lau Basin, revealing an unexpected relationship between the amount of in situ melt and the water content of the magma, indicating that subducted…
