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.

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.
Only Plinian and Pelean volcanic eruptions feature flow?
pyroclastic flow
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
Is a pyroclastic flow quiet?
That depends on the sense in which you mean silent. Pyroclastic flows are generate by explosive rather than "quiet" eruptions. However, no sound escapes the flows themselves. Their unusual acoustic properties ensure that the sound they produce remains trapped inside.
How fast can a volcano kill a person?
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.
What is more deadly lava or pyroclastic flow?
Pyroclastic flow.
How can pyroclastic flow be used in a sentence?
Beware the pyroclastic flow!

What volcano produces a pyroclastic flow?
an explosive volcano will usually have a pyroclastic flow

pyroclastic flow
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
What volcano has pyroclastic flow in addition to liquid lava?
the volcano that has pyroclastic flow in addition to liquid lava is the composite or stratovolcano.
What is a pyroclastic flow in volano?
Pyroclastic flow is gas that result from water mixing with loose material on the steep sides of a volcano.
Is a pyroclastic flow quiet?
That depends on the sense in which you mean silent. Pyroclastic flows are generate by explosive rather than "quiet" eruptions. However, no sound escapes the flows themselves. Their unusual acoustic properties ensure that the sound they produce remains trapped inside.
What are the similarities in a lava flow and a pyroclastic flow?
A lava flow is simply a flow of liquid rock down a slope that usually results from an effusive eruption. A pyroclastic flow is an avalanche-like flow of hot ash, rock and gas that moves down a volcano during an explosive eruption, The move much faster than lava flows and are far more dangerous.
