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.

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.

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 ...

The researchers point out that the previously known upper magma chamber was the immediate source of three cataclysmic eruptions of the Yellowstone caldera 2 million, 1.2 million and 640,000 years ...

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.

A new study shows a volcanic eruption of Yellowstone may be even less likely than we thought: Scientists have discovered a magma cap that may play a role in relieving volcanic pressure underground.

Though the existence of the magma reservoir beneath Yellowstone has been well-established, its location and contents are a lot less clear. That’s because researchers have long struggled to pinpoint ...

The discovery fills a missing link in Yellowstone’s volcanic plumbing system. But scientists said it doesn’t increase the risk of an eruption, which is estimated to happen every 700,000 years.
