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 ...

A new computer model of the magma plume reveals 7 million years of underground unrest, leading up to the creation of the dual magma chambers that animate the Yellowstone caldera in modern times, ...

A MAGMA chamber study has stunned Yellowstone scientists this week by dismantling previously accepted models of what hides beneath supervolcanoes like Yellowstone, the United States Geological ...

We can now use these new models to better estimate the potential seismic and volcanic hazards. ... — The 2,500-cubic mile upper magma chamber sits beneath Yellowstone’s 40-by-25-mile caldera, ...

It allowed them to develop a detailed model of the seething expanse beneath Yellowstone that makes it what it is. Here are the upper magma chamber and lower magma reservoir by the numbers.

We can now use these new models to better estimate the potential seismic and volcanic ... • The 2,500-cubic mile upper magma chamber sits beneath Yellowstone’s 40-by-25-mile caldera, ...

The newly discovered chamber is 4.5 times larger than the shallow reservoir already known and contains enough partially molten rock to fill the Grand Canyon 11 times.

The magma reservoir beneath Yellowstone volcano consists of two chambers — a shallow reservoir near the surface that's around 55 miles (90 kilometers) long and 25 miles (40 km) wide, and a ...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Madison Myers, assistant ...

Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park that's big enough to fill the Grand Canyon 11 times over.

JACKSON, Wyo. – New research indicates the magma chamber underlying Yellowstone National Park may not be as volatile as previously believed. University of Utah geophysicist Bob Smith and a ...

The newly discovered magma chamber — 12 to 28 miles underground — is four times bigger than the previously known chamber above it.
