Scientists have discovered important changes happening deep beneath Yellowstone National Park, home to one of the world’s largest volcanoes. These findings help us better understand the volcanic system beneath the park. Key Findings Made Simple Scientists used a method called magnetotellurics, which tracks electrical activity underground, to create a detailed map of molten rock (magma) beneath the park. They found that instead of one large pool of magma, there are seven smaller pools spread out underground. The largest of these pools has moved to the northeast part of the park. “When we used magnetotellurics, we were able to see, actually, … Continue reading Yellowstone Study Reveals Seven Magma Chambers, Largest Shifts Northeast, Eruption Risk Low
