A Surprise From the Supervolcano Under Yellowstone

New York Times, 2017: "The conditions that lead to supereruptions can emerge within a single human lifetime, according to a study of the volcano’s remnants in the national park. Beneath Yellowstone National Park lies a supervolcano, a behemoth far more powerful than your average volcano. It has the ability to expel more than 1,000 cubic kilometers of rock and ash at once — 250,000 times more material than erupted from Mount St. Helens in 1980, which killed 57 people. That could blanket most of the United States in a thick layer of ash and even plunge the Earth into a volcanic winter.
