Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are working out how and why it occurred to better understand these hazardous events.

For the first time, geoscientists detected the top of Yellowstone’s magma reservoir. It is active and dynamic, but not in danger of erupting, they found.

For decades, researchers in and around Yellowstone National Park have used seismic waves - imagine giving the region an MRI - to map the hot mush below the Earth's surface. Now a group of scientists ...

For decades, researchers in and around Yellowstone National Park have used seismic waves to map the hot mush below the Earth’s surface. Now, they're adding more to that toolkit.

Picture: Bennington et al., Nature, 2025 An apocalypse named Yellowstone Every 700,000 years or so, the Yellowstone supervolcano erupts. And it does so with a whoosh. Not a bang.

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 ...

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 outbursts ...
