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.
It is estimated that at times during the eruption the column of ash was 20 miles (32 km) tall. About 1 cubic mi (4 cubic km) of ash was erupted in about 19 hours. Vesuvius has erupted about three dozen times since 79 A.D., including a large, explosive eruption in 1631 that killed 4,000 people.bout 1 cubic mi (4 cubic km) of ash was erupted in about 19 hours.
