Beneath Yellowstone National Park lies something extraordinary—a giant underground chamber filled with molten rock, trapped gases, and intense heat. For years, scientists have known about this ...

The Yellowstone Volcano Observatory is a consortium of universities and agencies that monitors the Yellowstone supervolcano and conducts volcanic and geologic research.

Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are ...

However, when the scientists added temperature to their model, they found that if magma is consistently present over time so that the rock of the chamber is warm, size and shape matters less.

But stealthy eruptions only happen when all the conditions are in place—the right magma flow and the right chamber size, shape, and depth.

Is it safe to drink treated water from rivers in Yellowstone National Park? Well, that depends on whether there are any nearby thermal features.

Stealthy Volcanoes Are Quiet Until They Erupt Without Warning Signs – Here's Why Slow magma flows, small chambers, and hot rock all contribute to surprise volcano eruptions that occur without any ...

Yellowstone geophysicist Bob Smith has opined that if the volcano blew, "Devastation would be complete and incomprehensible," with the obliteration of Yellowstone Park, temperatures of hundreds of ...

On the night of May 31, an eruption from the Black Diamond Pool in Yellowstone National Park shot up about 20 feet, according to the Yellowstone Volcano Observatory.
