Are repeated tremors in North India a sign of a major earthquake?

This year's Earthquake was the biggest shock in North India. This went on for a long time. Many times people got shocked in this. This was the third decent blow in three months this year. By the way, every day 55 times in the world.

This year, this third shock was felt in Delhi-NCR and North India. However, this earthquake that occurred on March 21 was not only of high intensity but also lasted for 09-10 seconds. Its intensity was 6.6 while the center was the Kush area of ​​Afghanistan. This earthquake occurred on the day of Amavasya. The way earthquake Tremors are coming again and again in North India, are they indicating any major earthquake.

By the way, scientists of the Wadia Institute of Himalayan Geology had warned that there is a danger of a major earthquake in the Himalayan region, which can affect a large area. Professors of the Earth Science Department of IIT Kanpur had also expressed the possibility of a major earthquake in the future. They say that the collision between the Indian plate and the Eurasian plate is increasing under the earth.

Geological energy is being made in the Himalayan region

According to the scientists of Wadia Institute of Himalayan Geology, Dehradun, the Himalayan region from Hindukush mountain to Northeast India is very sensitive to Earthquakes. The epicenter of the present earthquake is also being told in the area of ​​Hindukush. By the way, experts say that geological energy and new landslide zones are being formed in the Himalayan region, which give rise to earthquakes.

There are an average of 55 earthquakes every day around the world.

According to the USGS, an American site that monitors earthquakes, from November 13 to the early hours of November 14, about 44 earthquakes occurred worldwide. In which the highest intensity earthquake was around 6.1 Japan. By the way, there are many earthquakes in the surrounding areas of Japan and Fiji.

This American site tells that there are about 55 earthquakes every day in the world, but most of them are mild. Whose intensity is around 5.0. Everyday 03 to 04 earthquakes are of more than 6 intensity.

The Kamcat Earthquake Catalog says that the number of earthquakes has increased in recent years, this is also because the sensitive instruments for measuring earthquakes are increasing all over the world and they are measuring earthquakes for a longer period of time, so their number is increasing. Is.

20,000 tremors are counted every year

The National Earthquake Information Center of America is counting 20,000 earthquakes every year all over the world. Earthquake records are being updated from the year 1900, they show that on an average 16 major earthquakes occur worldwide every year. In this, there are 15 such which are of 07 intensity on the Richter scale, while one is of 08 or more intensity.

Records of the last 40 years also show that earthquakes of longer duration have increased. In the year 2010, there were 23 major earthquakes.

Small tremors are not necessarily followed by big earthquakes.

In the year 2020, after two earthquakes that occurred one after the other in the US in January, it was said by Berkeley's Seismology Lab, 'On the basis of such small tremors, it is strongly It cannot be said that any big shock is going to come. Till now no authentic example of any big shock is found after a series of such small shocks.

Small tremors also come from fault line pressure

By the way, the laboratory had also said that if these small tremors of earthquake are coming due to any fault-line pressure, then it can be considered as knocking of a big tremor. Let us tell you that there are many fault zones all over the earth. This means that the plates meet each other at many places on the earth. An earthquake occurs when these plates move back and forth or up and down. India is divided into four zones according to the risk of earthquake. Geologists have placed Delhi and its surrounding area in Zone-4, which means an earthquake of up to 7.9 magnitude can occur here.

What is fault line

Explain that the joining place of tectonic plates is called fault line. Wherever the plates are connected, there is more collision and there are more earthquakes in those areas.

According to the studies of Berkeley's Seismological Laboratory, nothing can be said clearly about the big aftershocks after small tremors. If these are due to fault line pressure, then a big shock can come anytime and in case of normal adjustment, no such incident will happen for a long time. At the same time, scientists also talk about another theory. They believe that these small tremors can come to reduce the fault line pressure.

Do small tremors eliminate the possibility of a large earthquake

This reduces the possibility of major earthquake tremors. However, some scientists consider it just an illusion. According to American geologist Bergman, it may be that these are small tremors before the big earthquake. Similar tremors are felt even after big tremors. However, he says that it is impossible to make any guess about this.

There is a possibility of earthquake in a week after mild tremors

Bergman says that mild tremors of an earthquake indicate preparations to deal with the situation after a major tremor. After mild tremors, there remains a 10 percent chance of an earthquake of slightly higher intensity within a week. There is no need to panic with these small tremors, but after these you should be alert.

To know the cause of earthquake, it is necessary to understand the texture of the earth. The texture of the earth is divided into four parts, inner core, outer core, metal and crust. In this, the crust is the topmost layer of the earth, which is visible to the eyes. Rivers, oceans, mountains, hills, plateaus are all part of this crust. The land beneath the ocean is also a part of this crust.

Why do devastating earthquakes occur in the Indian subcontinent?

According to plate tectonic theory, the plates present in this crust are connected with each other. These are called tectonic plates. There are more than a dozen of them in number. Tectonic plates keep on moving. If it shakes a little, then no one even knows, but if it shakes a lot, then an earthquake occurs. Collision is more at the place of joining of plates and earthquakes also occur more in those areas.

These plates collide face to face and sometimes up and down. Sometimes these plates also collide diagonally. Destructive earthquakes have been occurring in the Indian subcontinent. Thousands of people lost their lives in the 2001 earthquake in Kutch, Gujarat. India is slipping about 47 mm a year. Earthquakes often occur in the Indian subcontinent due to the collision of tectonic plates. However, the movement of tectonic plates has slowed down due to the decrease in groundwater.
