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".
What else can I help you with?
Was Pompeii destroyed by a pyroclastic flow?
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.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Can you outrun a pyroclastic flow?
No. A pyroclastic flow can move at well over 100 mph.
Does a pyroclastic flow typically occur during a quiet or loud eruption?
Pyroclastic flow typically occurs during a violent eruption.
What does a pyroclastic flow sound like?
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.
How fast was pompeii pyroclastic flow miles per hour?
161 km
Was Pompeii destroyed by a pyroclastic flow?

What things leave volcanoes after they erupt?

What is more deadly lava or pyroclastic flow?

What is the term for lava flow that travels downhill at over 100mph?

What volcano produces a pyroclastic flow?

No. A pyroclastic flow can move at well over 100 mph.
How can pyroclastic flow be used in a sentence?
The pyroclastic flow from the volcano devastated the surrounding area, burying everything in its path under a blanket of ash and hot gases.
In which direction does a pyroclastic flow move away from a volcano?
A pyroclastic flow moves away from a volcano in all directions.
Does Lava flow faster from a violent volcano?
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.
