The eruption was catastrophic, lasting more than 24 hours. The eruption officially started on the morning of August 24, as molten rock and pumice began to be expelled from Mt. Vesuvius at a rate of 1.5 million tons per second. Copious amounts of rock and volcanic ash filled the atmosphere, turning day into night. It is estimated that about six inches of ash fell every hour.
Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii, Herculaneum and several other settlements.ount Vesuvius spawned a deadly cloud of stones, ash and fumes to a height of 33 km (20.5 mi), spewing molten rock and pulverized pumice at the rate of 1.5 Mt/s, ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima bombing.
