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.
What else can I help you with?
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 occurs during an quite eruption?
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
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.
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.
Is it true that pyroclastic flow typically occurs during a quiet eruption?
No. Pyroclastic flows are characteristic of explosive eruptions.
What happens when a explosive eruption hurls ash cinders bombs and gases out of a volcano?
A pyroclastic flow.
What is large amounts of hot ashdustand toxic gases ejected from a powerful volcanic eruption?
An explosive eruption often does produce such a phenomenon called a pyroclastic flow.
How does an explosive eruption products a pyroclastic flow?

Does a pyroclastic flow typically occur during a quiet eruption?
No, pyroclastic flows typically occur during explosive volcanic eruptions when hot gas and volcanic particles travel rapidly down the side of the volcano. Quiet eruptions, such as lava flows, do not produce pyroclastic flows.
An explosive eruption may produce a pyroclastic flow which is?
A pyroclastic flow is and avalanche-like mass of superheated ash, rock, and gas that races down a volcano's slopes at speeds that can reach well over 100 mph. These flows sear everything in their path.
How does an explosive erupton produce proclastic flow?
The explosive eruption has got to be powerful enough to create an eruption column (a Jet of hot gas and magma particles). This is shot into the atmosphere by the force of the eruption but the weight of the stuff in the eruption column is so great that it collapses back down on itself under gravity and runs down the sides of the volcano as a pyroclastic flow.
What volcano produces a pyroclastic flow?
an explosive volcano will usually have a pyroclastic flow
