GEOLOGY

Detailed explanation-1: -Such a landslide can destroy everything that is in its way, including houses, cars and bridges located at the foot of a slope. Many happen in alpine areas, where mud flows block rivers and lead to the flooding of whole valleys.

Detailed explanation-2: -Bulging ground appears at the base of a slope. Water breaks through the ground surface in new locations. Fences, retaining walls, utility poles, or trees tilt or move. The ground slopes downward in one direction and may begin shifting in that direction under your feet.

Detailed explanation-3: -Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

Detailed explanation-4: -Although gravity acting on an over-steepened slope is the primary reason for a landslide, there are other contributing factors: erosion by rivers, glaciers, or ocean waves create oversteepened slopes. rock and soil slopes are weakened through saturation by snowmelt or heavy rains.

Detailed explanation-5: -Landslides can cause high mortality and injuries from rapidly flowing water and debris. The most common cause of death in a landslide is trauma or suffocation by entrapment.
