Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment. “The western part of the Yellowstone ...

Magma reservoirs beneath volcanic systems like Yellowstone are not simply large tanks of molten rock, but rather are dynamic mixes of melt and crystals that can change drastically over time.

What will happen to Yellowstone once its rhyolite magma system shuts down? To understand the future, geologists look to the past — in this case, to Yellowstone Caldera’s older but ...

With all the talk of the current Yellowstone earthquake swarm, I thought it would worth it to write a post on the the structure and caldera – and why we get earthquake swarms that are ...

The cover of the Yellowstone Volcano Observatory’s Volcano and Earthquake Monitoring Plan for the Yellowstone Caldera System, 2022–2032, is available online to read.

The Yellowstone caldera, a giant crater caused by a previous eruption, measures 40 miles by 25 miles and sits in the northwest corner of Wyoming, in Yellowstone National Park.

Based on these data, Farrell and others (2014) have modeled a large, shallow zones of lower seismic velocity that they interpret as the magmatic system beneath the Yellowstone Caldera (see above).

Volcanic activity bubbling away beneath the Yellowstone National Park in the US appears to be on the move. New research shows that the reservoirs of magma that fuel the supervolcano's wild ...

They found four pockets together contain more liquid magma than was present during large, caldera-forming eruptions at Yellowstone in the past (one 2.8 million years ago, one 1.3 million years ago ...

It’s not often that nature provides a win-win for it and humanity, but the caldera system under Yellowstone National Park is certainly one. If harnessed, it could power much of America for ...

Yellowstone hasn't had a major eruption for hundreds of thousands of years, but it's still very much an active system. This newly discovered cap, which is 2.6 miles (3.8 kilometers) below the ...
