Mount Hood's mixing behavior is somewhat different than that of most other Cascade Range volcanoes, the researchers said, including Mount Hood's nearby, more explosive neighbor, Mount St. Helens.

Here, by using high-pressure mixing experiments and thermal calculations, we show that hybridization during single-intrusive events requires injection of high proportions of the replenishing magma ...

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

Geologists discover that hot and cold magmas mixing beneath Las Cañadas volcano in Tenerife triggers the volcano's massive, caldera-forming eruptions.

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 ...

“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 ...

Adam Kent: I think that magma mixing (also often called magma recharge) is a very widespread and effective way to trigger eruptions in many volcanic systems.

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.

Even through the cola is there, you still essentially have a glass of water. Same here—small volumes of chemically diverse magma, mixing with a large volume of ascending basalt," Stock said.

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