Tag: Supervolcano

A supervolcano is a large volcano that has the potential to produce an eruption of exceptional magnitude, typically defined as an eruption that ejects more than 1,000 cubic kilometers (240 cubic miles) of material. Supervolcanoes are characterized by their vast calderas, which can form when a magma chamber beneath a volcano empties during an eruption, causing the ground above to collapse. The term “supervolcano” is often associated with phenomena that can have global climatic effects, given the immense ash and gas emissions that can be released during such eruptions. Supervolcanoes are relatively rare and include notable examples such as Yellowstone in the United States and Toba in Indonesia. Their eruptions are less frequent than those of standard volcanoes, but their potential impact on ecosystems, climate, and human populations makes them significant geological features.
