Complex slope movements. Simple slide forms rarely occur in nature. Usually, slope movements are composed of combinations of the basic forms. Those combinations are called complex slope movements. The most common combination is a slump/earth flow. Destabilization on a slope can begin with a slump, which generally breaks down into smaller components. The downslope and basal portion of the slump can become highly fractured and dissaggregated. If the water content is high enough, those portions of the slump may begin to flow, resulting in a slump/earth flow. Other common types of complex slope movement include debris slump/debris-laden earth flow, rock slide/rock fall, and slump/topple. Multiple block slides/multiple flows, rock slides/talus flow, and rock fall/debris flows can also be found in areas of the State.
