Geophysicists have discovered a second, even more massive magma reservoir feeding the Yellowstone supervolcano, providing researchers with the most comprehensive picture yet of the volcanic system ...

The last major eruption of the Yellowstone supervolcano happened around 630 000 years ago, and was violent enough to create a collapsed crater, or caldera, over 60 km across. Though it shows no sign ...

YELLOWSTONE volcano’s terrifying magma chamber, deep beneath the supervolcano caldera, is full of radioactive molten rock, scientists have shockingly revealed.

New research has revealed when Yellowstone's supervolcano will erupt next, as it now contains a higher volume of magma than ...

Geoscientists discovered a magma cap acting as a "lid" 2.4 miles beneath Yellowstone. This magma cap traps heat and pressure, but also allows gas to vent, reducing eruption risk.

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 ...

Learning more about the magma under Yellowstone. Yellowstone is one of the planet's largest volcanic systems, a place where a plume of the Earth's molten core rises up through the solid rock of ...

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 ...

Underneath Yellowstone National Park, magma bubbles and flows. But exactly how close it is to the surface has long been a mystery to scientists — until now. For the first time, researchers have ...

Scientists have discovered a giant 'magma cap' under Yellowstone National Park. The cap is likely playing a critical role in preventing a massive volcanic eruption.

How can lightning and solar storms be used to map magma beneath Yellowstone? Through magnetotelluric imaging, which provides information about the amounts and locations of melt in the subsurface.
