Scientists see deeper Yellowstone magma

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 than the shallower, long-known magma chamber.

A new tool to understand volcanic supereruptions

To understand when and why volcanoes erupt, scientists study the rocks left behind by eruptions past. A method called geobarometry uses the composition of volcanic rocks to estimate the pressure and depth at which molten ...

How much magma is hiding beneath our feet?

Molten rock (or magma) has a strong influence on our planet and its inhabitants, causing destructive volcanic eruptions and generating some of the giant mineral deposits. Our understanding of these phenomena is, however, ...

New view of Rainier's volcanic plumbing

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier's deep volcanic plumbing and partly molten rock that will erupt again ...

Off-rift volcanoes explained

Volcanoes often develop outside the rift zone in an apparently unexpected location offset by tens of kilometers has remained unanswered. An international team of scientists has shown that the pattern of stresses in the crust ...

How Earth's devastating super-volcanoes might erupt

Devastating supervolcanoes can erupt simply due to changes that happen in their giant magma chambers as they slowly cool, according to a new study. This finding marks the first time researchers have been able to explain the ...

Iron melt network helped grow Earth's core, study suggests

(Phys.org) —Stanford scientists recreated the intense pressures and temperatures found deep within the Earth, resulting in a discovery that complicates theories of how the planet and its core were formed.
