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".
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.
Pyroclastic flow
No. A pyroclastic flow can move at well over 100 mph.
Pyroclastic flow typically occurs during a violent eruption.
Strangely, pyroclastic flows are silent. The speed of sound inside such a flow is quite slow, slower than the speed at which the flow moves. Because of this and other acoustic properties, all sound produced by a pyroclastic flow remains trapped inside of it.

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
Smoke, dust, rocks, lava, H2S, C02, Heat (pyroclastic flow), and a lot of noise.
Pyroclastic flow.
Pyroclastic flow
an explosive volcano will usually have a pyroclastic flow
No person killed the people of Pompeii; they were killed by an act of nature. They died because of the eruption of Mt. Vesuvius and its pyroclastic flow.
No. A pyroclastic flow can move at well over 100 mph.
The pyroclastic flow from the volcano devastated the surrounding area, burying everything in its path under a blanket of ash and hot gases.
A pyroclastic flow moves away from a volcano in all directions.
A violent volcanic eruption will produce pyroclastic flows, which are somewhat like avalanches of hot ash and rock, rather than lava flows. Pyroclastic flows are faster than any lava flow. When they erupt effusively, though, the lava is so viscous that it flows very slowly.
