Mudslides are debris flows or mudflows that are often triggered by storms in the mountains.  Debris flows (mudslides) are shallow landslides, saturated with water, that travel rapidly downslope as muddy slurries. The flowing mud carries rocks, trees, and other debris as it pours down the slopes.

Mountainous areas that have had recent forest fires are especially prone to mudslides because they have lost stabilizing trees and vegetation. Recurring mudslides can prolong the revegetation of an area for years.
