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.
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.

What are the types of volcanic flows?
pyroclastic and convectional.
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.
When does a pyroclastic flow happen after or before the eruption?
Generally pyroclastic flows happen during an eruption.
Are the hawaiian Islands a region or extensive pyroclastic flow?
They are a region. This islands themselves were formed primarily by lava flows. The volcanoes there rarely produce pyroclastic flows.
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.
Does pyroclastic flow have air poison?
Yes. Pyroclastic flows can contain toxic gasses such as sulfur dioxide.
Does a pyroclastic flow occur during during small earthquakes?
No. Pyroclastic flows are a result of volcanic eruptions.
