∙ 10y agoIt depends on the circumstances of their formation. Pyroclatic flows may be as hot as 1,800 degrees Fahrenheit, but thise resulting from phreatic eruptions might not be much hotter than the boiling point of water.

Which way does a pyroclastic flow move from a volcano?
Pyroclastic flows travel down the side of a volcano at a high rate of speed (upwards to 450 mph).
What is hot glowing rock that flows on cushion of hot gases?
pyroclastic flow
Are pyroclastic flows felsic or mafic?
Pyroclastic flows can be of any composition, but are more commonly felsic or intermediate.
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
What is the difference between pyroclastic flows and lava flows?
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.

How is a pyroclastic flow stopped?
A Pyroclastic Flow can't be stopped!! Even if you're there. If you are any where near a volcano when a Pyroclastic Flow occurs, you will most likely be dead within 30 seconds of seeing it.-Their speed may be as fast as the speed of sound.So Pyroclastic Flows can't be stopped, and aren't stopped.

What does a pyroclastic flow sound like?
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 was the speed of lava flow from mount vesuives on 79ad?
The 79 AD eruption of Mount Vesuvius did not produce lava flows. It was a Plinian eruption, produducing a massive ash plume and pyroclastic flows. Pyroclastic flows are not lava flows, they are masses of hot ash, rock, and gas that resemble avalanches. Nobody was able to clock the speed of these flows, but by comparing it to similar events it is likely that these flows moved at well over 100 mph.
Does Krakatoa produce lava or 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.
Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
Only plinian and pelean volcanic eruptions features what flow?
Plinian and Pelean eruptions poth commonly produce pyroclastic flows. However, such flows can also occur with Vulcanian eruptions.
What are the types of volcanic flows?
pyroclastic and convectional.
