Meteorologists know mixing cold air and warm air triggers powerful thunderstorms. Now, geologists have discovered a similar phenomenon at work beneath one of Europe's most hazardous volcanoes. The ...

Mixing magma . Geologists are already able to use things like gas emissions, the chemistry of hot springs, ground deformation, local earthquakes and other data to help predict when a volcanic ...

PAHOA, Hawaii --Lava oozing out of cracks for two weeks in rural Hawaii neighborhoods took on new characteristics as fresher magma mixed with decades-old magma, sending a flow toward the ocean ...

Then they looked at magma mixing before eruptions, finding a steady similarity in how the different layers of magma combined, one newer, hotter layer up to 9 miles beneath the 11,240-foot peak, ...

Magma in Earth’s crust is in a crystal-rich mushy state, yet must be fluidized before eruptions. Numerical simulations show that rapid injection of new magma into a reservoir creates a mixing ...

This suggests that there is a lot of magma mixing, cooling and reactivation of crystals and magma under the volcanoes, creating a wide diversity of compositions from a single volcano.

Afters months of waiting, I have finally been able to get my act together enough to post the answers to questions you posed to Dr. Adam Kent. If you remember back to the beginning of the fall, Dr ...

“This is definitely, without a doubt, the largest eruption since Mt. Pinatubo in 1991,” said corresponding author Scruggs, who studies magma mixing and eruption triggering mechanisms, and recently ...

The world's "sleeping giants" can wake up much quicker than thought, according to a new volcano model. Scientists believe the magma chambers—or reservoirs of molten rock—under dormant ...

Although assimilation, magma mixing, and high-pressure crystal fractionation impact differentiated magma compositions in all arcs, particularly continental arcs, these effects are minimized by ...

The change is attributed to new magma mixing with 1955-era magma in the ground, creating hotter and more fluid flows, scientists said.

PAHOA, Hawaii – Lava oozing out of cracks for two weeks in rural Hawaii neighborhoods took on new characteristics as fresher magma mixed with decades-old magma, sending a flow toward the ocean ...
