Mechanism of Landslides

 Mechanism of Landslides 

We must understand the mechanism of Landslides if we are residing in hilly areas.

What is mechanism of Landslides, we can say that it is the movement of mass of rocks , soil or debris down a slope under the influence of gravity.

Mechanism of Landslides 

Landslides occurs when the force of Gravity acting on the slopes exceeds

 the strength of the mass holding in a place.

The factors Responsible for Landslides :-

The factors Responsible for the landslides are  .

1. Heavy rainfall 

2. Earthquake.

3. Erosion.

4. Cloudburst.

5 Human Activities.

Human Activities :-  

1. construction of roads buildings , and other projects.

2. Deforestation 

Deforestation causes erosion hence landslides.

Landslide is a geological phenomenon involved in sudden movement of  mass of earth , rocks and debris down a slope under the influence of gravity 

We can understand the mechanism of Landslides from these figures.

1 Role of Gravity :- 

The gravity constantly pulls the mass down  the slopes as the  weight of the material exceeds the gravitational force the sliding starts  , hence rolling down the slopes .

Slope Stability :- 

Some factors affect the slopes stability.

Angle of Slope :- 

Steeper slopes are more prone to sliding because of greater gravitational pull .

Strength of the Soil Material :- 

Weathering action , erosion and water saturation weaken the structure of soil thus weak soils are more prone to sliding.

Water Content :-  

Water when comes in contact with soil the weight of the Soil Material gets increased , if the slopes are greater than the gravity  makes it to slide .

There are three types of slides 

1 . Slides 

2. Flows 

3 . Creep ..

In rainy seasons the hilly areas are more prone to sliding.

We can take some remidies which we will discuss in the next post .
