Plinian eruption
Avellino has suffered from seismic activity throughout its history and was struck hard by the earthquakes of 23 November 1980 and 14 February 1981. Avellino has also received ashfall from numerous eruptions of Vesuvius which lies almost due west; the city sits on type locality of pumice deposited from a Plinian eruption of Vesuvius about 3800 years ago.
