Explanation: 

Detailed explanation-1: -The eruption of Mount Vesuvius in 79 AD is one of the best-known in history. Buried the Roman settlements of Pompeii, Herculaneum, Oplontis, and Stabiae.

Detailed explanation-2: -A pyroclastic flow is the wall of death that entombed the ancient Roman city of Pompeii. These blackened, billowing clouds of 700°C gas, ash, and rock thunder down the slopes of erupting volcanoes at speeds up to 725 kilometers per hour, incinerating and demolishing most everything in their path.

Detailed explanation-3: -But in the summer of A.D. 79, the nearby Mount Vesuvius volcano erupted. It spewed smoke and toxic gas 20 miles into the air, which soon spread to the town. Almost overnight, Pompeii-and many of its 10, 000 residents-vanished under a blanket of ash.
