Magma in Yellowstone Caldera Bigger Than Previously Thought: Scientists

The volume of magma brewing under Yellowstone National Park could fill the Grand Canyon more than 11 times, scientists revealed in a newly published study this week.

"For the first time, we have imaged the continuous volcanic plumbing system under Yellowstone," said lead author Hsin-Hua Huang of the University of Utah, USA Today reported.

The researchers, who published their findings in the journal Science, used a technique called seismic tomography to map the caldera — a sort of underground volcano.

The caldera powers geothermal features across and around the part such as geysers, mudpots, steam vents, and hot springs, but hasn't erupted in 640,000 years.

Notably, the new picture of the caldera uncovered a second, deeper reservoir of magma previously unknown to scientists. The new reservoir is approximately 4.5 times bigger than the upper magma chamber.

During past eruptions, a blanket of ash fell over much of North America, measuring up to 3 feet deep in much of the northern Rocky Mountain region to less than an inch in places as far away as New York.

Along with their announcement, scientists sought to quell fears that the volcano is likely to erupt anytime soon.

"The existence of the second magma chamber does not make it any more or less likely that a large volcanic eruption at Yellowstone will occur. These findings do not change the current volcanic hazard at Yellowstone," University of Utah seismologist Jamie Farrell told The Associated Press, reported via Yahoo News.

"However, these new findings do provide us, and other researchers, the information needed to gain a better understanding of how magma moves from the mantle to the surface," he added.
