Ian Oliver provides an educational segment on supervolcanoes, differentiating them from regular volcanoes based on eruption power. He introduces the Volcanic Explosivity Index (VEI) and explains that a level 8 eruption is considered a supervolcano, also known as an apocalyptic eruption. He highlights the rarity of such events, occurring once every 100,000 years, and mentions the Yellowstone National Park supervolcano simmering beneath the surface.
