YELLOWSTONE NATIONAL PARK, Wyo. — The supervolcano at Yellowstone National Park has substantially more magma reservoir under the caldera than scientists previously thought, according to new research.
In addition, the newly found lava is flowing at shallow depths that fueled prior eruptions, according to a paper published Thursday inResearchers mapped the seismic wave speed below the Yellowstone volcano using a technique called seismic tomography.
The findings show it's possible there are some relatively small to moderate-size bodies of magma that are below Yellowstone that could be mobilized and expelled, Cooper said. Yellowstone tends to garner a lot of attention because of the potential for"catastrophic, explosive eruptions," Maguire said, but that's not the most common type of eruption in the park.
Despite the new discovery, the research does not indicate that an eruption will happen any time soon, the scientists said. There are no signs of"increased volcanic unrest" at Yellowstone, Maguire said.
