Understanding supervolcanoes and their apocalyptic potential

Fox Weather explains the difference between a regular volcano and a supervolcano, highlighting that supervolcanoes are categorized by their eruption power on the Volcanic Explosivity Index (VEI) reaching level 8. These "apocalyptic eruptions" can launch more than 240 cubic miles of material into the air, dramatically changing global weather for years. The segment mentions Yellowstone National Park as home to a simmering supervolcano, though its next eruption is not expected for 73,000 years.
