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.

Both a pyroclastic flow and a lava flow consist of extremely hot material release by a volcano anf flow downhill.

Both a lava flow and a pyroclastic flow are hot masses that are produced by volcanic eruptions and flow down hill.

What volcano has pyroclastic flow in addition to liquid lava?

the volcano that has pyroclastic flow in addition to liquid lava is the composite or stratovolcano.


Is block lava the same as pyroclastic flow?

No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.


Is mtn etna explosive or quiet and lava or pyroclastic flow?

Mount Etna has had both explosive and "quiet" eruptions and has produced lava flows, lava fountains, and pyroclastic flows.


What type of lava flow does mount meakan have?

it has pyroclastic flow and has small eruptions of ash.


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.


What type of lava is least likely to form a pyroclastic flow?

Pahoehoe lava, which has a low viscosity and flows more easily, is less likely to form a pyroclastic flow compared to a'a lava, which is more viscous and tends to fragment into pyroclastic material when flowing.


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.

Is pahoehoe considered pyroclastic debris?

No, pahoehoe lava is not considered pyroclastic debris. Pahoehoe is a type of basaltic lava that has a smooth, rope-like texture due to its low viscosity. Pyroclastic debris refers to fragmented material such as ash, volcanic rocks, and gases that are blasted out of a volcano during an explosive eruption.


Does Lava flow faster from a violent volcano?

A violent volcanic eruption will produce pyroclastic flows, which are somewhat like avalanches of hot ash and rock, rather than lava flows. Pyroclastic flows are faster than any lava flow. When they erupt effusively, though, the lava is so viscous that it flows very slowly.
