An update of the convection code ASPECT enables full coupling of plume dynamics with buoyancy effects of transition zone ...

"Our latest research shows that this is incorrect. Melt from a shared mantle source within the Hawaiian plume may be transported alternately to Kīlauea or Maunaloa on a timescale of decades." ...

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.

The mantle, by contrast, was seen as little more than a thick layer of hot rock, with the occasional plume pushing its way through. Now, the team on this new effort reports that a lot more is ...
