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 ...

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.

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.

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 ...

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 ...

Under Yellowstone lies a magma-filled formation that drives the national park’s famous geysers and other hydrothermal features. New research conducted by University of Utah geoscientists has ...

Scientist answer burning question about volcanic magma under Yellowstone Researchers from Rice University imaged the magma underneath Yellowstone and showed how it vents pressure, reducing the ...

And by finding a defined magma cap, researchers have also been able to determine that Yellowstone’s system remains lively and dynamic. “It hasn’t just been sitting there without any recharge ...

Yellowstone volcano: USGS finds seven huge magma chambers below supervolcano The Yellowstone Caldera is often referred to as the Yellowstone Supervolcano due to its colossal size; it's one of the ...

Yellowstone is behaving normally, as it has for more than 140 years, according to the Yellowstone Volcano Observatory. Yellowstone has not erupted in some 70,000 years, and the odds of a large ...
