What is a pyroclastic flow Why are they so dangerous?

Answer 1

Pyroclastic flows are dangerous. They can travel down slope at over 150 mph, somtimes much faster if propelled by a lateral blast. Temperatures inside the flows are often over 1,000 degrees Fahrenheit. Anyone caught in one of these will burn to death.

Answer 2

A pyroclastic flow is an flow of superheated ash, often the result of a eruption column collapsing under gravity.

Pyroclastic flows can be several 100s degrees centigrade and travel very fast ( 10s metres per second in some cases) over all types of land and sea and jump over hills up cliffs destroying everything in their path.

Answer 3

Pyroclastic flows move very fast, generally at over 100 mph, so you can't outrun them and the can travel pretty far in some cases. They are also extremely hot. Anyone caught in a pyroclastic flow will die almost instantly.

Answer 4

A pyroclastic flow is and very hot, fast-moving mass of ash, rock, and gas that moves down the sides of a volcano. Pyroclastic flows move too fast for people to evacuate and anyone caught in one will almost certainly burn to death. The force of these flows can level concrete buildings.

Answer 5

Pyroclastic flows are dangerous for a variety of regions. Temperatures inside a pyroclastic flow are extremely high, sometimes exceeding 1000 degrees Celsius (1800 degrees Fahrenheit), making them unsurvivable. These flows move incredibly fast, often over 160 km/h (100 mph), making them nearly impossible to escape and giving almost no warning. Their enormous momentum also means that they can surge across valleys and over ridges, making their paths difficult to predict. They also carry an enormous amount of force and are often capable of destroying sturdy buildings.

Answer 6

A pyroclastic flow is essentially an avalanche of ash, rock, and gas that flows down the slopes of a volcano at great speed. Temperatures inside these flows can be well over 1,000 degrees Fahrenheit, which is unsurvivable for any human, plant, or animal. They often move at over 100 mph, making it nearly impossible to escape if you are in the path of one. They can also bury an area in a thick deposit of material that can then be welded together by the intense heat of the flow, forming a material that can be as hard as concrete.

Answer 7

Pyroclastic flow is deadly because it's made up of hot poisonous gases and rock moving over 400 miles per hour and reaching close to 2000 degrees F.
