Landslides are the downward and outward movement of a slope composed of earth materials such as rock, soil, artificial fills. Other names of landslides are rockslide, debris slide, slump, earth flow and soil creep.
Man induced landslides
During construction of roads and mining activities huge portions of fragile mountainous areas are cut and thrown into adjacent areas and streams. These land masses weaken the already fragile mountain slopes and lead to landslides called man induced landslides.
Causes of landslides
3. Removal of vegetation
In the sloppy area creates soil erosion, which leads to landslides.
2. Underground mining
Cause subsidence of the ground.
Due to the movement of buses and trains in the unstable sloppy region cause landslides.
4. Addition of weight
Addition of extra weight (or) construction on the slope areas leads to landslide.
5. Ground water level
Over exploitation of ground water also leads to landslides.
Harmful effect of landslides
Landslide increases the turbidity of nearby streams, thereby reducing their productivity. Destruction of communication links.
Loss of habitat and biodiversity.
Loss of infrastructure and economic loss.
