The first large-scale picture of the electrical conductivity of the underground molten rock that feeds the Yellowstone supervolcano suggests that the plume beneath the volcanically active area, known for geysers and hot springs, is even bigger than it appeared in images made with earthquake waves. In the past 2 million years, three eruptions at Yellowstone have spewed enough volcanic ash to cover half of North America. The new study doesn't speculate about the chances of another cataclysmic caldera eruption at Yellowstone but it gives new perspective on the deep reservoir of fiery material that feeds eruptions. read more
