The Yellowstone Supervolcano is located in Yellowstone National Park, primarily in the U.S. state of Wyoming. It is one of the largest active volcanic systems in the world, formed by a series of massive eruptions over the past 2.1 million years. The most recent major eruption occurred approximately 640,000 years ago, creating the Yellowstone Caldera, a large crater that is a key feature of the park. The supervolcano is monitored closely by the United States Geological Survey (USGS) due to its potential for future eruptions. It features geothermal activity, including hot springs and geysers, such as the famous Old Faithful. Scientists study this area to better understand volcanic behavior and assess any risks to nearby communities.
