Seismic evidence for a 1000 km mantle discontinuity under the Pacific

This study uses reverse-time migration full-waveform seismic imaging to reveal a thinned transition zone and a 1000-km mid-mantle discontinuity under the Pacific near Hawaii which they link to the upper boundary of upwelling plume material.
