20 areas of India are likely to experience an earthquake with a magnitude of 8

  • Scientists of the Wadia Institute of Himalayan Geology indicated the possibility of an earthquake
  • An earthquake of reactor scale 8 or higher can strike at any time
  • Earthquake probability is highest in Ramnagar in Uttarakhand, Kangra in Himachal Pradesh and Assam

After the recent earthquake in Turkey, scientists around the world are expressing fears about the future. Scientists at the Wadia Institute of Himalayan Geology, also in India, have estimated 20 areas in the Himalayas where earthquakes of reactor scale 8 or more can strike at any time. Let us tell you that the building here shakes due to an earthquake of magnitude 5 or more. In such a situation, if an earthquake of magnitude 8 occurs, we cannot even imagine the damage caused by it. The magnitude of the earthquake in Turkey was 7.9.

Senior Scientist of the Institute Dr. According to RJ Perumal, there may be 20 areas prone to major earthquakes in an area of ​​about 2000 km in the Himalayas and about half a dozen areas in India.

The probability of such an earthquake is highest in Ramnagar in Uttarakhand, Kangra in Himachal Pradesh and Assam. This is because the energy cannot escape even though the tension is running under the earth of these areas. Dr. Perumal says that in the year 1255 there was an earthquake of eight to nine reactors in the Ramnagar area. No major earthquake has been recorded here since then.

Similarly in the year 1255 a very powerful earthquake (8.0 to 9.0) occurred in Nepal with geological structure. Then there were major earthquakes in 1831, 1934 and 2015. Kangra in Himachal, which falls in the same sub-seismic belt, has not experienced any earthquake since the 1905 earthquake (7.8 on the Richter scale).

Central Nepal and Assam province of the country also fall in one belt. Small earthquakes as well as large earthquakes occur here at short intervals. Except for the 1255 earthquake in Nepal, the duration of the last three major earthquakes was 51 to 81 years, and the last 2 major earthquakes in Assam along the same route occurred between 51 and 81 years.

Why do earthquakes occur?

To know the answer to this, first you have to understand the structure of the earth. The whole earth is located on 12 tectonic plates. Lava is present under these tectonic plates. These 12 plates float on this lava. When lava collides with these plates, the energy released is called an earthquake.

It is also understood as the outermost layer of the earth which is divided into 12 plates. These plates are constantly changing. Sometimes these plates collide with each other while migrating. Due to which earthquake shocks are felt. Due to which the ground also slips.

Millions of years ago, India was not close to Asia, but due to earthquakes on land, India is moving towards Central Asia by about 47 mm per year. About five and a half million years ago a collision was so massive that the Himalayas were formed.

India was a big island then. Floating in the ocean for more than 6,000 kilometers, the island collided with the Eurasia tectonic plate and formed the Himalayas. The Himalayas are the smallest mountain range in the world.

According to scientists, the Himalayan regions are becoming very vulnerable to earthquakes due to geological changes. Due to this both the plates are constantly pushing against each other, causing instability in the region. But the question arises why the Himalayan earth plates are not stabilizing? To find out the answer, efforts are still on to understand the collision that took place millions of years ago, through a software called ‘underworld code’.

How does this software work?

A software called ‘underworld code’ works on the data. By filling the data in this software, it is being seen how the situation changed before and after the collision. Also looking at how powerful those changes were physically. So far the ‘underworld code’ has revealed that the density of the surface of the Indian plate is higher than that of the interior. Due to which India is moving towards Central Asia.

India is divided into four parts on the basis of earthquake risk

India is divided into four zones in terms of earthquake risk. First Uttarakhand, second Srinagar area of ​​Kashmir, third Himachal Pradesh and fourth a part of Bihar. On the other hand, Gujarat’s Kutch and six states of the North-East fall in the highly sensitive category. They are kept in zone five. Zone five means that these areas have a high potential for dangerous earthquakes. Five major earthquakes have occurred in the Himalayan region since 1934.

A magnitude 8 earthquake releases 1,000 times more energy

Scientists have spoken of an earthquake with a magnitude of 8 or more in India. A magnitude 8 earthquake releases 1,000 times more energy than a magnitude 7 earthquake. An earthquake with a magnitude of 8 is considered very dangerous. It affects a very large area, and is felt for a long time. Buildings are completely destroyed by this earthquake. Pillars, walls and heavy furniture fall due to the shock of this earthquake. Earthquakes of magnitude 8 or more occur once a year.
