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.
Pyroclastic flow
No. A pyroclastic flow can move at well over 100 mph.
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.
Pyroclastic flow typically occurs during a violent eruption.
Lava is molten rock at earth's surface. A pyroclastic flow is an avalanch-like flow of hot ash, rock, and gas that moves down a volcano's flanks at great speed.
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.
Pyroclastic flow.
Pyroclastic flow
an explosive volcano will usually have a 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.
the volcano that has pyroclastic flow in addition to liquid lava is the composite or stratovolcano.
Pyroclastic flow is gas that result from water mixing with loose material on the steep sides of a volcano.
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.

a pyroclastic flow is where u squeeze a massive spot (somewhat like a supervolcano) so hard it erupts and all the puss dribbles down ur facebook and drips off ur chin into the Atlantic ocean (ur bath tub)
