Researchers estimate magma under supervolcano

Washington State University researchers "spike" a Yellowstone hot spring with deuterium, a stable isotope, to calculate water and heat flowing out of the springs and estimate how fast magma is recharging beneath the Yellowstone supervolcano. The material had no environmental impact and was done with a permit from the National Park ServiceWSU geologists have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano.

Scientists now have a better understanding of a key factor of what’s underneath the massive caldera: a pool of basalt magma continually recharging the system.

Ancient Inland Northwest volcanic eruptions blocked out sun, cooling planet

Palouse Falls (c)WSU Photo ServicesThe Pacific Northwest was home to one of the Earth’s largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet, Washington State University researchers have determined.

“This would have been devastating regionally because of the acid-rain effect from the eruptions,” said John Wolff, a professor in the WSU School of the Environment. “It did have a global effect on temperatures, but not drastic enough to start killing things, or it did not kill enough of them to affect the fossil record.”

The research, which was funded by the National Science Foundation, appears in Geology, the top journal in the field. Starting 16.5 million years ago, they say, vents in southeast Washington » More …
