Yellowstone’s magma chamber is mostly made of a light-colored rock called rhyolite. It spreads out over an area roughly 55 miles long and 30 miles wide and reaches down to a depth of about 10 miles.

“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 ...

Yellowstone’s fascinating volcano Yellowstone’s volcanic system has fascinated geologists for decades. They have long suspected molten rock lurks close to the surface. In 2022, another group of ...

There is a very sharp transition marking the magma chamber top at about 3.8 kilometers (2.4 miles) depth beneath the northeastern part of the caldera near the Yellowstone River.

Results published by Duan and Schmandt show a razor‑sharp boundary, less than 100 metres thick, marking the magma chamber roof at about 2.4 miles (3.8 kilometres) beneath Yellowstone’s ...

There is a very sharp transition marking the magma chamber top at about 3.8 km (2.4 miles) depth beneath the northeastern part of the caldera near the Yellowstone River.

The answer is important to fundamental science questions about magma reservoirs as well as for understanding the potential hazards from Yellowstone. And, it’s just a darn interesting question, too!
