In short
On August 24, 79 AD, Mount Vesuvius erupted catastrophically, burying the Roman cities of Pompeii and Herculaneum under volcanic ash and pumice within hours. The disaster killed thousands of residents instantly and preserved their final moments in ash, creating an unparalleled archaeological record of Roman life.
How it unfolded.
The five-minute version
What actually happened.
Mount Vesuvius is a somma–stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 km (5.6 mi) 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.
