Debris flows are accelerated downhill by gravity and tend to follow steep mountain channels that debouche onto alluvial fans or floodplainsThe front or head of a debris-flow surge often contains an abundance of coarse material such as boulders and logs that impart a great deal of frictionTrailing behind the high-friction flow head is a lower-friction mostly liquefied flow body.

Volcanism has continued in the caldera after the climatic eruption of Mount Mazama. A mudflow or mud flow is a form of mass wasting involving very rapid to extremely rapid surging flow of debris that has become partially or fully liquified by the addition of significant amounts of water to the source material.
