Study Notes
Landslides
- Landslides are a natural disaster that can cause destruction of life and property in hilly terrains.
Events Associated with Landslides
- Landslides often occur in conjunction with events such as heavy rainfall, earthquakes, and volcanic eruptions.
Causes of Landslides
- Heavy landslides that block the flow of a river can be caused by erosion, deforestation, and human activities such as mining and construction.
Consequences of River Blocks
- The formation of river blocks due to landslides can have potential consequences such as flash floods, changes in river courses, and damage to infrastructure.
Factors Triggering Landslides
- The massive landslide in Pangi village near Reckong Peo in Kinnaur district of Himachal Pradesh was triggered by factors such as heavy rainfall, geological instability, and human activities.
Mitigation Techniques
- Hazard mapping is a mitigation technique that involves locating areas prone to landslides to take preventive measures.
- Construction of retention walls is a mitigation technique that involves building walls to stop land from slipping and prevent landslides.
- Increasing vegetation cover is a mitigation technique that involves planting trees and vegetation to arrest landslides and prevent soil erosion.
