The caldera started forming during an eruption around 17, 000 ( or 18, 300 ) years ago and was enlarged by later paroxysmal eruptions, ending in the one of AD 79 . This structure has given its name to the term " somma volcano ", which describes any volcano with a summit caldera surrounding a newer cone.
