The explosive power of supervolcanoes explained

Ian Oliver explains what defines a supervolcano, differentiating it from regular volcanoes by its immense eruption power on the Volcanic Explosivity Index (VEI) scale. He describes apocalyptic eruptions, which are Level 8 events, capable of launching over 200 cubic miles of material into the atmosphere and drastically altering global weather for years. Oliver notes the rarity of such events, with the last occurring 27,000 years ago, and mentions a supervolcano beneath Yellowstone National Park.
