What is the difference between a pyroclastic flow and a pyroclastic surge?
A pyroclastic flow is a dense, fast-moving avalanche of hot gas, ash, and rock fragments that travels down the slope of a volcano. A pyroclastic surge is a turbulent cloud of hot gases and ash that moves laterally across the ground at high speeds during a volcanic eruption. Pyroclastic flows are more dense and destructive, while pyroclastic surges are less dense and can cover larger areas.
