- A pyroclastic flow (also known as a nuée ardente) is a common and devastating result of some volcanic eruptions. The flows are fast-moving fluidized bodies of hot gas, ash and rock (collectively known as tephra) which can travel away from the vent at up to 700 km/h. The gas is usually at a temperature of up to 1000 degrees Celsius. The flows normally hug the ground and travel downhill under gravity, their speed depending upon the gradient of the slope and the size of the flow.
