Why do so many earthquakes occur in Delhi-NCR and what is its connection with Nepal?

The tremors of the earthquake in Nepal on Tuesday afternoon scared the people. Its effect was also visible in Delhi-NCR. National Center for Seismology (NCS) the epicenter of this earthquake Nepal Told K Kalika. The intensity of the earthquake has been measured at 5.8 on the Richter scale. The epicenter of the earthquake was 10 kilometers inside the ground surface. For 30 seconds its effect was felt in many cities of the country apart from Nepal.

Apart from Delhi, its effect was seen in many cities of Uttar Pradesh and Uttarakhand. Talking about Delhi-NCR, earthquake tremors were felt here many times last year. Why does this happen here, scientists have also answered it.

Why do earthquakes occur in Delhi-NCR?

Why earthquake tremors are felt several times a year in Delhi-NCR. On this, Professor Chandan Ghosh of the Civil Engineering Department of IIT Jammu says, Delhi is in the northern zone. This is called Zone-4 of the earthquake. Which is considered very sensitive. Due to the change in the environment, the earthquake centers are also changing. This is happening due to change in tectonic plates.

He says, Delhi is close to the Himalayas, which were formed by the meeting of the tectonic plates of India and Eurasia. Due to movement in these plates, cities like Delhi-NCR, Kanpur and Lucknow are most sensitive to earthquakes. Sohna, Mathura and Delhi-Moradabad have three fault lines near Delhi, due to which the possibility of a major earthquake cannot be ruled out.

Nepal to Delhi connection

A report says, it is the same in the case of Nepal. The effect of the center of the earthquake formed here is more on those parts of India which are already in sensitive areas. The amount of damage will depend on the intensity of it. The intensity of the earthquake in Nepal has been measured at 5.8 on the Richter scale. That’s why there is no serious damage of any kind there.

In the media report, Senior Professor and Geoscience Engineering Expert Prof. Department of Civil Engineering at IIT Kanpur. Javed N Malik says, Presently the tectonic plates in the Himalayan range are becoming unstable. That’s why such earthquakes will continue to occur in the coming times. This is the reason that the effect of the earthquake coming in Nepal will be visible on Uttarakhand and Delhi-NCR.

Why and how do earthquakes happen?

Before understanding the earthquake, one has to understand the structure of the plates present under the earth. The whole earth is situated on 12 tectonic plates. The energy released when these plates collide is called an earthquake. Actually, these plates present under the earth rotate or slide at a very slow speed. Every year 4-5 mm slips from its place. During this, some plate slips from under someone, and some goes away. During this, when the plates collide with each other, the condition of earthquake is created.

How is the epicenter of an earthquake determined?

Under the surface of the earth, where the rocks break or collide, it is called the center or hypocenter or focus of the earthquake. From this place the energy of the earthquake spreads in the form of vibrations. This vibration is just like, waves are created by throwing a pebble in a calm pond. The place where the line connecting the center of the earth to the center of the earthquake intersects the surface of the earth is called the epicenter. That is, that place on the surface of the earth is closest to the center of the earthquake.
