Landslides are the downward movement of a slope composed of earth materials such as rock, soil or artificial fills. Landslides are also called rock-slide, debris-slide, slump, earth-flow or soil-creep

During construction of roads and mining activities huge portions of mountainous fragile areas are cut down and thrown into adjacent areas and streams. These land masses weaken the already fragile mountain slopes leading to man-induced landslides.

EFFECTS OF LANDSLIDES:

Landslides increase the turbidity of nearby streams, thereby reducing their productivity

Destruction of communicative links

Loss of habitat and biodiversity

Loss of infrastructure and economic loss

CAUSES OF LANDSLIDES

Removal of vegetation - Deforestation in slopes creates soil erosion leading to landslides

Underground mining activities cause subsidence of the ground

Movement of heavy vehicles in areas with unstable slopes causes landslides.

Addition of weight by construction on slopes causes landslides.

Over exploitation of groundwater also leads to landslides.
