Kashmir, Himachal and North Eastern states are at greater risk of earthquake than Delhi

According to the National Center for Seismology, earthquake tremors were felt all over North India at 2.28 pm on January 24. Its intensity was 5.8 on the scale. The epicenter of the earthquake is said to be 10 km inside the ground in Nepal. On the other hand, on January 5, earthquake tremors were felt in North India as well. Then the earth shook till Jammu-Kashmir. The magnitude of this earthquake was measured at 5.9 and its epicenter was the Hindukush region of Afghanistan.

This earth of ours is generally divided into three layers (crust, mantle and core) but the 50 kilometer thick layer from above is also scientifically divided into several sections which are called tectonic plates. This tectonic also has 7 surfaces (plates). Which is not stable and keeps on moving continuously. When these plates collide with each other, then these plates also break and due to their collision, a large amount of energy is released, due to which the earth vibrates, which we know as earthquake.

Why this vibration continuously in India?
According to the Bureau of Indian Standards (BIS), many areas in India are considered sensitive to earthquakes. Which are divided into four zones (Zone 5, Zone 4, Zone 3 and Zone 2). 59 percent of the country is in the earthquake risk zone, which is included in zones 5, 4 and 3. Zone 5 covers 11 percent of the total land area of ​​the country, which is considered the most active. Zone 4 covers 18 percent, Zone 3 covers 30 percent of India’s area. Zone 2 covers 41 percent which is the least active. It is worth noting here that all these zones do not fall in any particular state or region. Different areas of the same state may fall in different zones. One thing should be made clear here that apart from this, there is a zone first, in which there is no danger, but no city in India is free from the danger of earthquake.

Know, which states fall in which zone?

Zone 5:
It has been considered the most dangerous and sensitive zone of the country. It includes all the northeastern states of the country, Andaman and Nicobar Islands, part of Jammu and Kashmir (Kashmir Valley), western part of Himachal Pradesh, eastern part of Uttarakhand, Rann of Kutch in Gujarat, part of northern Bihar.

Zone 4:
This zone also comes in the dangerous category, in which the intensity of earthquake can remain up to 8. It includes Ladakh, remaining parts of Jammu and Kashmir, remaining parts of Himachal Pradesh and Uttarakhand, parts of Haryana, parts of Punjab, Delhi, Sikkim, northern parts of Uttar Pradesh, Bihar and a small part of West Bengal, Gujarat, western Some parts of Maharashtra near the coast and a small part of western Rajasthan fall in this zone.

Zone 3:
Kerala, Goa, Lakshadweep group, parts of Uttar Pradesh and Haryana, remaining parts of Gujarat and Punjab, some areas of West Bengal, western Rajasthan, Madhya Pradesh, some areas of Bihar, northern part of Jharkhand and Chhattisgarh, Maharashtra, Odisha, Some areas of Andhra Pradesh, Telangana, Tamil Nadu and Karnataka come.

Zone 2:
This zone is considered the least sensitive. In this comes the remaining part of Rajasthan, Haryana, Madhya Pradesh, Maharashtra, Odisha, Andhra Pradesh, Telangana and Tamil Nadu. There is no danger of an earthquake of more than 4.9 magnitude here.

how many types of earthquake are there
Tectonic earthquakes: These are small movements in the Earth’s crust. When they collide, the vibrations and shocks are felt. This earthquake occurs most frequently in India.
Volcanic earthquakes: These are the earthquakes which are less frequent than tectonic ones. These occur before or after a volcanic eruption. This happens when rocks come to the surface and mix with magma coming out of a volcano.

Impact earthquake:
These earthquakes mostly occur in underground mines. Actually the pressure created inside the rocks due to the explosion is the primary reason.

Burst Earthquake: This earthquake is not completely natural but also unnatural. For example, when an atomic bomb explodes, the tremor in the earth is called an explosion earthquake. On the other hand, even if a meteor hits, an earthquake can occur.

120 earthquakes occurred last month
According to the data collected by the National Center for Seismology (NCS), in the last month i.e. from December 1 to December 31, 2022, 120 earthquakes were reported from 152 stations near them. But 113 such earthquakes were recorded which originated in India and its surrounding Asian countries. At the same time, out of total 120 earthquakes, 36 percent and 43 percent earthquakes have been recorded in 3.0-3.9 and 4.0-4.9 magnitude. While there have been three earthquakes of magnitude 5.0-5.9.

What can happen at what intensity?
From 0 to 1.9 intensity it is detected only by seismograph.
Mild tremor is on the 2 to 2.9 magnitude scale.
Any person feels vibration at 3 to 3.9 intensity.
At magnitude 4 to 4.9, windows could shatter, and frames hanging on walls could fall.
Furniture may shake at magnitude 5 to 5.9.
Foundations of buildings can crack at 6 to 6.9 magnitude.
At magnitude 7 to 7.9 buildings collapse, underground pipes burst.
At magnitude 8 to 8.9, large bridges including buildings also collapse.
On the Richter scale of 9 and above, complete devastation can occur.
