Supraeruptions
Supraeruptions, commonly referred to as supereruptions, are extremely large volcanic eruptions that eject more than about 1000 cubic kilometers of magma as tephra, ash, pumice, and volcanic gases. They occupy the upper end of the volcanic explosivity scale (VEI-8) and are among the most powerful geological events known. Such eruptions are rare and leave lasting geological and climatic signatures in the Earth’s history.
These events typically involve large silicic magma bodies and caldera-forming processes. The eruption expels vast volumes
Notable examples include the Oruanui eruption of the Taupo volcanic system in New Zealand about 26,000 years
Because such events are infrequent on human timescales, they are mainly studied through the geological record.
