Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

"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." ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

“Yellowstone Caldera Chronicles” is a weekly column written by scientists and collaborators of the Yellowstone Volcano ...

Yellowstone and Hawaiʻi. These systems a well known for producing large volumes of magma through time and leaving chains of volcanic features in their wake, although they do so in very different ways.

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.

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

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 ...
