Yellowstone Supervolcano (Wyoming, United States) Effects of a major eruption: When the Yellowstone Caldera, or supervolcano, in Yellowstone National Park erupts again, its effects would be worldwide, the U.S. Geographical Survey said.
The eruption would entail more than dangerous lava flows and could be expected to kill as many as 90,000 people immediately and spread a 10-foot (3-meter) layer of molten ash as far as 1,000 miles (1,609 kilometers) from the park. Rescuers probably would have a tough time getting in there.
