A supervolcano is a large volcanic system capable of producing an eruption with a magnitude of 8 on the Volcanic Explosivity Index. These eruptions can release thousands of cubic kilometers of material, significantly impacting the environment and climate. Supervolcanoes are often found in areas with a high geothermal activity, such as the Yellowstone Caldera in the United States.
The formation of a supervolcano typically involves the accumulation of magma beneath the Earth's crust. When pressure builds up, it can lead to a catastrophic eruption. While supervolcanoes are rare, their potential for widespread destruction makes them a subject of scientific study and monitoring.
