Yellowstone Supervolcano

The Yellowstone Supervolcano is a massive volcanic system beneath Yellowstone National Park, characterized by a large magma chamber that fuels occasional supereruptions—massive, landscape-altering events releasing hundreds to thousands of times more ash and gases than typical eruptions. While it has erupted three times in the past 2.1 million years, these events occurred long ago, and current monitoring indicates no imminent threat. The volcano's activity is part of a natural geothermal system, powering features like geysers and hot springs. Scientists closely monitor it to understand its behavior and assess potential hazards, but a supereruption in the near future is considered highly unlikely.
