About 2000 people are feared dead due to landslides in Papua New Guinea. In such a situation, the question arises whether scientists do not have any such method, with the help of which they can find out about land slides in advance like earthquakes and rain. Let us tell you in this article today how challenging it is for science to find out about landslides in advance.
How does a landslide occur?
Landslide is a geological phenomenon. Actually, when the stones, soil and debris present under a part of the ground start sliding downwards, it is called a landslide. Usually landslides occur in hilly areas. Often the landslide incident occurs due to earthquake or heavy rain. Actually, when an earthquake occurs, the ground starts shaking from inside.
In such a situation, the accumulation of soil and stones starts breaking and due to this the soil starts sliding from top to bottom. When there is heavy rain, the soil becomes wet and the bond of the soil with stones and trees starts weakening and then a time comes when the soil starts sliding downwards along with the debris.
Humans are also responsible for landslides
Apart from natural events, humans are also responsible for landslides. The way trees are being cut on the mountains and new constructions are being done every day, due to this the soil of the mountains has become loose. Apart from this, explosions to build roads on the mountains, heavy cutting of mountains for stones are also some of the main reasons for this.
Prediction of landslides
Every year thousands of major incidents occur across the world due to landslides. Lakhs of people lose their lives due to this. But even after this, it is very difficult to find out about landslides in advance. In fact, it is almost impossible to map where and at what time a landslide may occur on the mountains. Yes, it is true that if the government wants, it can map some areas and study the soil there and warn people in advance that this place is in the danger zone in case of landslides.
