According to Suetonius, he kept singing until he finished his song; Tacitus records that the theater collapsed shortly after it was evacuated. Fifteen years later, when four days of minor tremors preceded the most catastrophic volcanic eruption in Roman history, the people living around Mount Vesuvius paid little attention. As Pliny the Younger later wrote, the tremors "were not particularly alarming because they are frequent in Campania." Around 1:00 p.m. on a day in autumn of 79 AD, Vesuvius exploded. The eruption destroyed the Roman towns of Pompeii and Herculaneum, killed untold thousands, and gave its name to the Vesuvian type of volcanic eruption -- the kind that sends columns of hot gas and ash into the stratosphere.
