How fast does lava flow?
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 mphEverything above is credit to User:Bassman162
Why is pyroclastic flow dangerous and what is it?
A pyroclastic flows is a hot, fast-moving mass of ash, rock and gas that moves down the slopes of a volcano during an explosive eruption. Pyroclastic flows are dangerous because they are extremely hot, often hot enough to kill a person instantly. They also move very fast, often at speeds of 100 to 200 miles per hour, which makes it nearly impossible to escape from the path of one in time. Even if it were not for the heat, many pyroclastic flows carry enough force to level buildings.
Which is faster a lava flow pyroclastic flow or lahar?
Pyroclastic flows move much faster than lava flows and carry much more momentum. This means there is little time tog et out of the way, and that they can pass over barriers that would stop or deflect lava flows. They can also carry more material. A single pyroclastic flow can bury an area to several meters thick in a matter of seconds.
Are lava flows the greatest hazard of volcanoes?
No. The most dangerous products of volcanic eruptions are pyroclastic flows. While lava flows can be very destructive, they generally move slowly and can only move downhill. Pyroclastic flows avalanche-like clouds of hot ash, rock, and gas. They move very quickly, often exceeding 100 miles per hour, leaving little chance of escape. Their great momentum means that they can cross valleys, hills, and ridges that would stop or redirect lava flows.
How fast does shield volcanoes lava flow?
Lava flows have been clocked at thirty kilometers per hour on the island of Hawaii. Lava usually travel at speeds of ten to three hundred meters per hour from shield volcanoes.

What type of lava flow did mt st helens have?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was a plinian eruption that produced aolumn of ash and pyroclastic flows. Pyroclastic flows are avalanche-like masses of hot ash, rock, and gas that rase away from an erupting volcano at speeds that can reachinto the hundreds of miles per hour.

What is a pyroclast flow of the volcano?
a pyroclastic flow is a cloud of volcanic bombs, volcanic blocks, volcanic ash, and lapilli. these flows can achieve speeds at over 125 miles per hour and can be more than 750 degrees Celsius.
