Scientists decipher the magma bodies under Yellowstone

Using supercomputer modeling, University of Oregon scientists have unveiled a new explanation for the geology underlying recent seismic imaging of magma bodies below Yellowstone National Park.

New evidence for plume beneath Yellowstone National Park

A pair of researchers from the University of Texas has found what they claim is evidence of a plume beneath Yellowstone National Park. In their paper published in the journal Nature Geoscience, Stephen Grand and Peter Nelson ...

New study challenges traditional theory of Yellowstone formation

Recent stories in the national media are magnifying fears of a catastrophic eruption of the Yellowstone volcanic area, but scientists remain uncertain about the likelihood of such an event. To better understand the region's ...

Study bolsters theory of heat source under Antarctica

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet. Although the ...

Hot spot at Hawaii? Not so fast

Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like those that formed the Hawaiian Islands aren't moving as fast as recently thought.

Study challenges widely accepted theory of Yellowstone formation

Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held ...

Plate tectonics thanks to plumes?

"Knowing what a chicken looks like and what all the chickens before it looked like doesn't help us to understand the egg," says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and ...
