Lava can reach supersonic speeds in some highly explosive volcanic eruptions. Lava speed is mostly dependent on the lava's viscosity, whether it's runny or sticky. Most runny lava flows are probably less than 10 miles per hour. The more viscous, the slower the flow, depending on slope and other conditions.
What else can I help you with?
What is lava movement?
Lava movement refers to the flow of molten rock on the Earth's surface, typically during a volcanic eruption. The movement of lava can vary in speed, from slow-moving oozing flows to fast-moving streams of molten rock. Lava flow direction is influenced by topography, gravity, and the viscosity of the lava.
What is the slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Does all lava flow at the same speed?
No. The fastest lava flows on earth have been recorded at Mount Nyiragongo in the Congo flowing at 60 mph (100 km/h). In most cases, however, lava flows very slowly. Blocky lava flows are the slowest, moving at speeds comparable to glaciers.
What is moving Lava?
Felsic magma.
What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
What type of lava is most dangerous?
the most dangerous type of lava is sticky lava because slow moving acid lava is more vicious
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 is coolslow-moving lava called?
Felsic magma.

How is the speed of lava measured?
