Avellino Eruption
The Avellino eruption of Mount Vesuvius refers to a Vesuvian eruption in 1995 BC. It is estimated to have had a Volcanic Explosivity Index, VEI of 6, making it larger and more catastrophic than Vesuvius's more famous and well-documented Eruption of Mount Vesuvius in 79 AD, 79 AD eruption. It is the source of the Avellino pumice ( it, Pomici di Avellino) deposits extensively found in the comune of Avellino in Campania. Characteristics of the eruption The "assessment of volcanological factors" in one scientific study reconstructs a minimum eruption time of 3 hours in which an initial explosion raised a column of ash and deposited about 0.32 km3 of white pumice ("the white pumice phase"), while a second, more intense explosion raised a column to depositing 1.25 km3 of grey pumice ("the grey pumice phase"). These pumices appearing in Apulian pottery can be used to establish the relative chronology of pottery phases. A 2008 study of the Lithology, lithofacies (deposits ...

Mount Vesuvius
Mount Vesuvius ( ; it, Vesuvio ; nap, 'O Vesuvio , also or ; la, Vesuvius , also , or ) is a somma-stratovolcano located on the Gulf of Naples in Campania, Italy, about east of Naples and a short distance from the shore. It is one of several volcanoes forming the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera, resulting from the collapse of an earlier, much higher structure. The eruption of Mount Vesuvius in AD 79 destroyed the Roman cities of Pompeii, Herculaneum, Oplontis, Stabiae, and several other settlements. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of , erupting molten rock and pulverized pumice at the rate of per second. More than 1,000 people are thought to have died in the eruption, though the exact toll is unknown. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus. Vesuvius has ...
