Yes, Pompeii was partially destroyed by a pyroclastic flow during the eruption of Mount Vesuvius in 79 AD. The deadly flow of superheated gases and volcanic debris engulfed and buried the city, preserving it under layers of ash.
Yes a pyroclastic flow did destroy pompeii yes it did it flattened the Italian village of pompeii. it is a mixture of hot gas volcanic rock and ash
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
Pyroclastic flow can travel at speeds as great as 450 MPH (700 KM/h)
Very quickly. A pyroclastic flow can approach half the speed of sound. People exposed to the temperatures inside a pyroclastic flow can die almost instantly.
No. Most pyroclastic flows don't go for more than a few miles.

Pyroclastic Flow
The cloud that enveloped Pompeii in 79 AD is known as a "pyroclastic flow." This deadly phenomenon was a fast-moving current of hot gas and volcanic matter released during the eruption of Mount Vesuvius. The intense heat and speed of the flow caused immediate fatalities among the city's inhabitants, contributing to the tragic loss of life during the eruption.
There have been a number of historically documented eruptions that produced what we now know were pyroclastic flows, but they were first described scientifically after the 1902 eruption of Mount Pelee, which wiped out the city of St. Pierre on the French colonial island of Martinique. The flows were called nuee ardente by the French, meaning "glowing cloud".
