LANDSLIDE :-
• The sudden movement of rock, debris or earth along the slope is called landslide. There are wide varieties of the names given to the denudation process whereby soil or rocks are displaced along the slope by mainly gravitational forces and landslides are one them. Landslides refer to the movement of mass of rock, debris or earth down the slope, when the shear stress exceeds the shear strength of the material.
The various causes of landslides are: -
Natural causes:-
• Landslides are generally associated with natural calamities like earthquake, volcanic eruptions, floods, cloudburst, etc.
• Long spell of rainfall
• Loose soil cover and sloping terrain
Anthropogenic causes-
• Rapid urbanization and changes in land use patterns
• Rampant deforestation and mining activities like blasting and quarrying, etc.
• Increased industrialisation leading to climate change and weather disturbances
• Change in river flow due to construction of dams, barriers, etc.
