Wikipedia
Pyroclastic flow
A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s) but is capable of reaching speeds up to 700 km/h (190 m/s). The gases and tephra can reach temperatures of about 1,000 °C (1,800 °F). Pyroclastic flows are the most deadly of all volcanic hazards and are produced as a result of certain explosive eruptions; they normally touch the ground and hurtle downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope.

Pyroclastic flow
A pyroclastic flow is a fast-moving current of hot gas and rock, which reaches speeds moving away from a volcano of up to 700 km/h. The gas can reach temperatures of about 1,000 °C. Pyroclastic flows normally hug the ground and travel downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. They are a common and devastating result of certain explosive volcanic eruptions.

Examples of pyroclastic flow in a Sentence
Temperatures in the pyroclastic flow can exceed 700 degrees (Celsius) and volcanic ash can rain down on a 15 kilometer (9.32 miles) radius. That could cause more mud flows and nearby rivers to burst their banks.
