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 Caldera, a volcanically active region under and around Yellowstone National Park, has long been the subject of research, speculation and science fiction regarding the possibility of a ...

Geoscientists have discovered a magma cap at Yellowstone National Park that is likely playing a critical role in preventing a massive eruption in one of the largest active volcanic systems in the ...

(NEXSTAR) — There have long been questions about when Yellowstone’s volcanic system could see an eruption, especially after a massive hydrothermal explosion was caught on camera last summer.

The discoveries challenge the popular image of Yellowstone as a ticking time bomb with a single massive underground pool of molten rock.

Scientists have studied Yellowstone National Park’s magmatic system for decades, which makes the iconic geysers, mud pots and various hydrothermal wonders possible. But it wasn’t until recently that a ...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Brandon Schmandt, professor of Earth, ...

However, Yellowstone's magma chamber isn't just a giant pool of molten rock. What's called a partial melt — small interconnected zones of magma filling fractures and small spaces — fills 6 to 7 ...

In a groundbreaking study, scientists have revealed that supervolcanoes may erupt far more suddenly than previously thought—raising serious concerns about global volcanic risks. Researchers focused on ...

A small town in Idaho sitting near the Yellowstone supervolcano has been rocked by an early morning earthquake, possibly signaling a future eruption. The US Geological Survey (USGS) reported that a ...
