Geologists had previously thought that super-eruptions only occurred 100,000-200,000 years after forming. Evidence from the new study by researchers at Vanderbit University suggests that, after a giant magma pool forms, it may erupt after only a couple hundred

Yellowstone National Park hosts a variety of hot springs and geysers, all powered by a plume of molten rock under its surface. At times in the past, that plume has powered activity that was quite a bit less scenic: massive eruptions that have been capable of covering
