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.

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 ...

Brandon Schmandt, a professor of earth, environmental, and planetary science at Rice University, told Nexstar that scientists have long known that there is magma beneath Yellowstone.

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 ...
