How do you mitigate landslides Upsc?

Deforestation and other human activities also induce landslides. The adverse effect of landslides can be reduced by checking deforestation on mountain slopes, following building codes for such areas, and by avoiding the construction of buildings on steep slopes.

Why do landslides occur Upsc?

Human activities like mining or quarrying remove the vegetation cover and soil gravel. This lowers the groundwater retention capacity. Also, it increases the risk of flooding. Therefore, landslides occur due to loose debris or excess floods during an earthquake and heavy rainfall, respectively.

How does land slide happen?

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.

How do you control land sliding?

improving drainage. reducing the angle of the slope. excavating to unload the top of the slope. building a protective berm or wall to buttress the bottom of the slope.

How can we stop landslides in India?

An increase in forest cover is a must in community lands to reduce the hazard of landslides. People must store the excess water in catchment areas. People must restrict the grazing of their animals.

What are 5 things you can do to prepare for a landslide?

Know Your Area’s Risk for Landslides. Prepare a Landslide Disaster Plan. Know the Warning Signs. Evacuate Immediately. Wait for the All Clear. Reclaim the Land. Know Where to Get Emergency Care When You Need It.

What are the 5 causes of landslide?

Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

Who is responsible for landslides?

What causes landslides? Landslides can be caused by human and natural factors. Natural factors can include lithology, structure, slope, land cover, seismicity and rainfall precipitation, while human factors can include deforestation, improper land use and unplanned activities.

What is the conclusion of landslide?

Conclusion. Landslides are a dangerous hazard that can cause serious damages, death, injuries and affect a variety of resources. By understanding the different types and causes of landslides it can help us predict future occurrences and reduce the potential effects.

Can land slides be predicted?

To be able to predict landslides, scientists have developed slope stability models to analyze the risk locally. More recently, NASA has created a preliminary algorithm to map landslide hazards globally using satellite measurements of rainfall, land cover and other surface variables.
