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.

What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Is pahoehoe considered pyroclastic debris?
No. Pahoehoe is considered a lava flow. Pyroclastic debris consists of volcanic ash, pumice, and lapilli rather than lava flow material.
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 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.
What are the materials give off by volcano during eruptions?
lava + pyroclastic flow mainly
What is more deadly lava or pyroclastic flow?
Pyroclastic flow.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
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 pahoehoe considered pyroclastic debris?
No. Pahoehoe is considered a lava flow. Pyroclastic debris consists of volcanic ash, pumice, and lapilli rather than lava flow material.
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.
What type of lava flow does mount meakan have?
it has pyroclastic flow and has small eruptions of ash.
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 is the difference between tephra and pyroclastic flow?
Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.
Does Krakatoa produce lava or pyroclastic flow?

What are the natural hazards on mt stromboli?
?pyroclastic flow, lava, ash, cinder, and bombs
How are lava and pyroclastic classified?
Both lava and pyroclastic material are classified as rocks. Lava is molten rock and pyroclastic material is various debris. There is Basaltic lava, Andesitic lava, Dacite lava, and Rhyolitic lava.
