IIT Delhi has prepared a web application for predicting and mapping landslides. In this way, a landslide history record for any area can be prepared within 3 to 5 minutes. It was created by Professor Manabendra Saharia of IIT Delhi. The name of this application is Cascade. Doctoral scholar Nirdesh also expressed support.
The app maps landslide areas. Currently, landslide mapping in the country is done virtually by visiting landslide sites. This takes a lot of time. There are many places that are difficult to reach. This web application can do the job using satellite imagery in 3 to 5 minutes.

What benefits will this bring?
1. Landslide mapping will make it easier to find out whether landslides have occurred in any location before. It is also believed that if a landslide has occurred somewhere before, it will happen again there. Many times, people build houses on mountains due to lack of information about this. Roads have been built. thereby causing losses. Historical records of landslides anywhere are available through this app.
2. The web application also helps in post-landslide recovery. With this app it is easy to know how much damage has been done to houses, railway lines or roads in that place. Its data will prove very helpful in insurance claims.
3. Suppose people live on the side of a mountain where landslides do not usually occur. On the other side of the same mountain, no one lives. Small landslides continue to occur there. It’s hard for people to go there. No one has this information. This means that landslides can occur at any time on the other side where people live. Its mapping can be done through this application.

What is a landslide?
Landslides don’t just happen in mountainous areas. Occurs in areas from the Himalayas to Kerala. This is the natural process by which most land or mountains move. Loss of balance and stability. Then he swiped down. Or scroll faster. The reason behind this is the way mountains are naturally formed.
Land movement occurs when mountains form
When a mountain forms, a large amount of land moves from one place to another. Whenever an object reaches a higher energy state, it tries to move toward a lower energy state. thus maintaining stability. The same thing happens when landslides occur in mountainous areas. Be it Himachal Pradesh, Uttarakhand or Kerala. Landslides are happening.

Why do so many landslides occur?
The frequency of extreme weather events has increased over the past 10-15 years. Therefore, the hillside is unstable. To get it we swipe from top to bottom. Commonly known as landslides. When landslides occur on a large scale, they are called landslides.
If the area moved is so large, can it be called a landslide?
When 10 square meters of land slides together, it is considered a landslide. It’s a hillside like this, and there aren’t such solid rocks underneath. There is loose soil on top. There are fewer trees and plants on this land. As more water falls from above. Then it slid.
Landslides can have only two causes. The first earthquake and the second heavy rain. Nothing else has changed. If landslides do not occur due to these two natural causes. So it couldn’t have come from anything else. Because the geographical conditions are stable. Humans are destroying it. Contributing to climate change and haphazard construction.
What are the main causes of landslides?
Wherever landslides occur in Himachal Pradesh, Uttarakhand, Sikkim or Kerala, the reason behind them is extreme rainfall. This means extreme rainfall. Apart from this, the Chardham project is also an important cause for Uttarakhand. These roads have caused disasters in other states as well. In Kerala, extreme rainfall emerged as the cause.
Whenever tourism, human activities, and random construction increase in high-altitude areas, the risk of landslides increases. Be it Kerala or the Himalayas. Extreme weather events caused by climate change and rising temperatures play a major role in this.
Mountains also structure and behave differently
The Himalayan region has layered plateaus. This means the soil is fragile. The soil of the Deccan Plateau is composed of lava and magma and is called cotton soil. That’s pretty loose, too. However, the parent rock of the Deccan Plateau is much stronger than that of the Himalayas. If the height. Lack of vegetation. This situation will definitely cause landslides if the soil is loose.

Landslides behave differently in different locations. Therefore, it is difficult to predict them in advance. Because the slope of each mountain is different. It is very difficult to build an early warning system to determine who will fall and when. Almost impossible.
Some early warning systems are based on sensors that estimate the speed of landslides on a daily basis. Their accuracy is great. But the system installed in India is for landslides. They are completely dependent on rainwater. Only an approximate picture of the landslide can be given. They cannot tell when or where a landslide will occur.
