Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.

The supervolcano at Yellowstone National Park has substantially more magma reservoir under the caldera than scientists previously thought, according to new research. In addition, the newly found ...

At the Yellowstone supervolcano, the magma reservoir under the caldera at Yellowstone National Park holds a lot more melt than scientists previously thought.

Now, Yellowstone's magma is on the move, according to research published in the journal Nature, where a team of scientists said they found a build-up in a corner of a vast 50 kilometre by 70 ...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Madison Myers, assistant ...

Recent research reveals that Yellowstone’s magma chamber contains significantly more liquid magma than scientists previously estimated, suggesting that the supervolcano might be closer to ...

Yellowstone National Park sits atop a giant supervolcano that has experienced three giant eruptions in the past two million years or so.

The research also found that the percentage of semi-liquid or melt material in Yellowstone’s magma chamber is possibly higher than previously thought, suggesting it could be as high as 28%.

There is more magma under the Yellowstone caldera than previously thought, according to a new study from researchers at the University of Illinois-Urbana Champaign published in Science Dec. 1. But ...

Scientists have studied Yellowstone National Park's magmatic system for years, but a new view of the magma chamber shows the long-dormant supervolcano is not at immediate risk of eruption.

Clusters of earthquakes can be frequent and contribute to about 50% of the overall seismic activity in the Yellowstone area. How big is the magma chamber under Yellowstone?

Scientists have studied Yellowstone National Park's magmatic system for years, but a new view of the magma chamber shows the long-dormant supervolcano is not at immediate risk of eruption.
