During an explosive eruption, a volcano sends out superheated ash, gas, and rock. Depending on the nature of the eruption, pyroclastic flows can develop in three ways:
A lateral blast directly ejects the flow, though this is a rather rare event. In another scenario, dense pyroclastic material erupts and spills out of the vent or over the crater rim. In still other cases a vertical eruption column collapses and material flows downhill.
In all cases the flow involves a mass of ash, rock, and gas that is too dense to rise on its own, and instead hugs the ground.
Most pyroclastic flows are produced during explosive eruptions of stratovolcanoes.

∙ 9y agoA pyroclastic flow is a quickly-moving stream of hot gas and rock. An explosive eruption is able to produce a pyroclastic flow because the gasses continue to build up pressure until they finally explode.

What kind of eruption has an pyroclastic flow?
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
Can non explosive volcanoes have pyroclastic flows?
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
Does a pyroclastic flow typically occur during a quiet eruption?
No. Pyroclastic flows are a product of explosive eruptions.
A pyroclastic flow typically occurs during a quiet eruption?
That is False. A pyroclastic Flow typically occurs during a explosive erupiton.
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.

Does a pyroclastic flow typically occur during a quiet eruption?
No. Pyroclastic flows are a product of explosive eruptions.
What is the name of the flow of gas from a very explosive volcano?
The name of the explosive outflow of gas from a volcaic eruption is a Pyroclastic Flow, however it can also be called a Pyroclastic Surge.
A pyroclastic flow typically occurs during a quiet eruption?
That is False. A pyroclastic Flow typically occurs during a explosive erupiton.
Is it true that pyroclastic flow typically occurs during a quiet eruption?
No. Pyroclastic flows are characteristic of explosive eruptions.
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
Does a pyroclastic flow typically occurs during an quite eruption?
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
What happens when a explosive eruption hurls ash cinders bombs and gases out of a volcano?
A pyroclastic flow.
What volcano produces a pyroclastic flow?
an explosive volcano will usually have a pyroclastic flow
What do you call the fast-travelling stream of hot gas and fragmental material that is produced during an explosive volcanic eruption?
Pyroclastic flow
When does a pyroclastic flow happen after or before the eruption?
Generally pyroclastic flows happen during an eruption.
