What causes of landslides?

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.

What are the different types of landslides?

Landslides in bedrock

Rock falls. Single and small rock falls from cliffs build up to form aprons of scree or talus, sometimes developing over long time periods.
Rock slope failures. This group of landslides varies greatly in features.
Rotational landslides.
Debris flows.
Creep.
Solifluction.
Translational slides.

Is landslide a hazard?

Landslide dams can be extremely dangerous because they are usually highly unstable. As the water builds up behind the dam, the landslide becomes saturated with water and can break catastrophically, flooding all areas downstream with little or no warning.

How can we prevent landslides?

There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.

Is landslide a natural disaster?

Landslides occur when masses of rock, earth, or debris move down a slope. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters.

What are the most common landslides?

Debris flows, sometimes referred to as mudslides, mudflows, lahars, or debris avalanches, are common types of fast-moving landslides. These flows generally occur during periods of intense rainfall or rapid snowmelt.

What are the hazards caused by landslides?

Landslides include a wide range of phenomena involving downslope ground movement, such as rockfalls, deep slope failure, shallow debris flows, and avalanches.

What are effects of landslides?

The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.
