Debris flows with volumes ranging up to about 100,000 cubic meters occur frequently in mountainous regions worldwide. The largest prehistoric flows have had volumes exceeding 1 billion cubic meters (i.e., 1 cubic kilometer). As a result of their high sediment concentrations and mobility, debris flows can be very destructive.
The difference between these two concepts is subtle but important. The landslide causes are the reasons that a landslide occurred in that location and at that time and may be considered to be factors that made the slope vulnerable to failure, that predispose the slope to becoming unstable. The trigger is the single event that finally initiated ...
[1] As had occurred in Yungay, huge boulders were thrown hundreds of metres across the valley, destroying everything in their path. [5] The largest single boulder found in the slide, near the site of Ranrahirca, weighed 14,000 tonnes (31,000,000 lb). [1] The slide dammed the Río Santa, causing it to back up in a 2 km (1.2 mi) long lake.

Cellular faces, also known by the name of "crib faces" are special supporting walls made of head grids prefabricated in reinforced concrete or wood (treated with preservatives). The heads have a length of about 1–2 m and the wall can reach 5 m in height. Compacted granular material is inserted in the spaces of the grid.
The United States' National Multi-Agency Coordination Group (MAC) establishes National Preparedness Levels throughout the calendar year to help assure that wildland firefighting resources are ready to respond to new incidents. Preparedness Levels are dictated by burning conditions, fire activity, and especially resource availability.
