Lava actually flows very slow. About 1 to 2 miles per hour with the fastest being about 5 miles per hour. Lahars, a mix of rock debris and water, flows very fast, usually around 60 miles per hour. Pyroclastic flow, a mix of hot gases, ash, and rocks that form a dense super heated current can reach speeds greater than 100 mph

Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
How fast does pillow lava flow?
Im not sure but I think its not fast but not slow so in the middle
How fast does lava and ash flow from kilauea?
Video of Krakatoa shows blocky lava flows. These flows are slow that you can barely see their movement if you can see it at all.
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
Is there a difference between lava and lava flow?
Lava is molten rock at earth's surface, whether it is in a lava flow, a lava pool, or a lava dome. A lava flow is lava that is actively flowing downhill.

How fast does dacite lava flow compared to mafic lava?
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
How fast does pillow lava flow?
Im not sure but I think its not fast but not slow so in the middle
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 eruption produces a gentle flow of lava?
Shield volcanoes produce fast flowing lava. They erupt frequently, but eruptions are gentle because the lava is so thin and does not trap gas in the volcano.
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.
How fast dose lava flow?
it all depends on the silica content which makes high or low viscosity
Is dike a type of lava flow?
No, a dike is not a type of Lava flow.
How long can magma flow until cooling?
Magma flows for a long period of time but named lava when out of the ground. It depends how fast the lava is travels, but you can usually run from it:)
