Pyroclastic flows going down Mayon Volcano, Philippines, in 1984.

A pyroclastic flow (also known as a pyroclastic density current)is a common result of volcanic eruptions. The flows are currents of hot gas, or tephra, during an eruption that sometimes causes rock falls.

They are extremely dangerous and mostly deadly.
