SSC MTS EXAM

Detailed explanation-1: -Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.

Detailed explanation-2: -The Appalachian Mountains, the Rocky Mountains and the Pacific Coastal Ranges and some parts of Alaska and Hawaii have severe landslide problems. Any area composed of very weak or fractured materials resting on a steep slope can and will likely experience landslides.

Detailed explanation-3: -By definition a trigger is an external stimulus such as intense rainfall, earthquake shak-ing, volcanic eruption, storm waves, or rapid stream erosion that causes a near-immediate response in the form of a landslide by rapidly increasing the stresses or by reducing the strength of slope mate-rials.
