GEOLOGY

Detailed explanation-1: -Positive effects of landslides. As with all natural hazards, landslides offer some important service functions. Thus, the positive effects of landslides are: creating new habitats, increasing biodiversity, providing raw materials and can be good tools for studying the environment.

Detailed explanation-2: -Landslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.

Detailed explanation-3: -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.
