The Avellino eruption of Mount Vesuvius occurred c. 1995 BC. It is estimated to have had a VEI of 6, making it larger and more catastrophic than Vesuvius's more famous and well-documented 79 AD eruption. It is the source of the Avellino pumice (Italian: Pomici di Avellino) deposits extensively found in the comune of Avellino in Campania.
