This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath the central Pacific showing the relationship between seismically-slow "plumes" and channels imaged in the study.

A mysterious find on Easter Island ... blobs of rock that slowly rise from the deep Earth's mantle—so-called mantle plumes.

Conducted by researchers from Ocean University of China and Tohoku University, Japan, the work combines innovative seismic methodologies to map mantle flow patterns, slab-plume interactions ...
