On the morning of June 21, visitors at Grand Prismatic Spring in Yellowstone National Park observed a bison slip into a ...

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.

This method allowed scientists to locate the top of Yellowstone’s magma chamber. They found it sits about 3.8 kilometers (12,500 feet) below the surface.

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 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 ...

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger ...

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.

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.

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.
