Pyroclastic flow is gas that result from water mixing with loose material on the steep sides of a volcano.
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 typically occurs during a violent eruption.
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.

a pyroclastic flow.
Yes, of course Krakatoa has a pyroclastic flow. Every volcano has an pyroclastic flow, which can travel up to at huge speeds. Krakatoa's pyroclastic flow raced an amazing 200 mph over 20 miles of open sea. Yes Krakatoa has pyroclastic flows but not all volcanoes produce pyroclastic flows, only Mt. St. Helens type volcanoes usually composed of andesite. Kilauea for example does not produce pyroclastic flows because it is composed of basalt, the lava flows out easily.
