单词	supervolcano
释义	supervolcano /ˈsuːpəvɒlˌkeɪnəʊ / noun (plural supervolcanoes or supervolcanos) An unusually large volcano having the potential to produce an eruption with major effects on the global climate and ecosystem: the possibility of a supervolcano erupting is terrifying, but the odds are fairly long against it happening in our lifetimes... A supervolcano would release enough to cover the entire UK under four metres of ash. The eruption of the supervolcano Toba approximately 74,000 years ago is thought to have wiped out much of our genetic diversity by causing the extinction of many human groups. There is enough volcanic material below the surface to match the largest of the supervolcano's three eruptions over the last 2.1 million years, Farrell said.
