Ash Clouds Over the Bay of Naples

Mount Vesuvius is a stratovolcano rising above the Bay of Naples in southern Italy. Its eruption in AD 79 buried the Roman towns of Pompeii, Herculaneum and Stabiae under ash and searing flows, preserving them for centuries. The volcano grew inside the older caldera of Monte Somma.

Pliny the Younger watched from across the bay and described a towering cloud shaped like a pine tree. Because of his letters, huge explosive eruptions are called Plinian. His uncle, Pliny the Elder, a Roman commander, died while trying to rescue people. Scholars long dated the eruption to August, but new evidence, including an inscription found in 2018, points to autumn.

Vesuvius last erupted in 1944, damaging Allied aircraft during World War II. The Vesuvius Observatory, founded in 1841, is the oldest volcano observatory in the world. Hundreds of thousands of people live in the red zone around the volcano, so detailed evacuation plans are in place.
