GEOLOGY

Detailed explanation-1: -Landslides include a wide range of phenomena involving downslope ground movement, such as rockfalls, deep slope failure, shallow debris flows, and avalanches. Gravity acting on a slope is the primary cause of landslides, but there are other important and dynamic factors that serve as triggers.

Detailed explanation-2: -In the United States, landslides and debris flows result in 25 to 50 deaths each year. The health hazards associated with landslides and mudflows include: Rapidly moving water and debris that can lead to trauma; Broken electrical, water, gas, and sewage lines that can result in injury or illness; and.

Detailed explanation-3: -They usually start on steep hillsides as shallow landslides that liquefy and accelerate to speeds that are typically about 10 mph, but can exceed 35 mph. The consistency of debris flows ranges from watery mud to thick, rocky mud that can carry large items such as boulders, trees, and cars.

Detailed explanation-4: -falls. topples. slides (rotational and translational) flows.
