Yellowstone super-volcano has a different history than previously thought, according to a new study by a Virginia Tech geoscientist. Scientists have long thought that Yellowstone Caldera, part of the Rocky Mountains and located mostly in Wyoming, is powered by heat from the Earth’s core, similar to most volcanoes such as the recently active Kilauea volcano in Hawaii. However, new research published in Nature Geoscience by Ying Zhou, an associate professor with the Virginia Tech College of Science’s Department of Geosciences, shows a different past.Yellowstone super-volcano eruptions were produced by gigantic ancient oceanic plate.
