Quick Answer
A debris flow is a fast-moving mixture of water, soil, rock, and debris that rushes downhill like wet concrete.
The Full Story
Debris flows can be triggered by intense rainfall, rapid snowmelt, volcanic eruptions, or the failure of landslide-dammed slopes. They move through channels and valleys, often with enough force to carry boulders and destroy structures in their path. Because they can occur suddenly and with little warning, they are a major hazard near steep terrain and volcanic areas. In some volcanic settings, similar flows are called lahars when volcanic material is involved.
