The formation of Heart Mountain near Cody is a story of a block of rock the size of Rhode Island moving at 700 mph, an ...

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 system is one that’s been stagnant for a long time.” The volcano’s largest eruption, which earned it the title of a supervolcano, occurred 2.1 million years ago.

Recent research reveals that Yellowstone’s magma chamber contains significantly more liquid magma than scientists previously estimated, suggesting that the supervolcano might be closer to erupting ...

Scientists have studied Yellowstone National Park's magmatic system for years, but a new view of the magma chamber shows the long-dormant supervolcano is not at immediate risk of eruption.

The most recent eruption, 630,000 years ago, was estimated to be 1,000 times more powerful than the 1980 Mount St. Helens eruption, which caused over $1 billion (£800 million) in damage.

The Yellowstone Caldera is a 70 by 45 kilometre-wide crater in northwestern Wyoming, blasted out of the Earth’s crust some 640,000 years ago in a cataclysmic eruption.

Despite widespread fears of a catastrophic "supervolcano" eruption, scientists at the Yellowstone Volcano Observatory (YVO) have suggested that any eruptive event there would likely look far ...

“The Yellowstone system is one that’s been stagnant for a long time.” The volcano’s largest eruption, which earned it the title of a supervolcano, occurred 2.1 million years ago.

It’s still possible that the northeastern portion of the park could erupt in a massive explosive eruption similar to those that have occurred at Yellowstone in the past 2.1 million years.
