Why earthquake comes and what is the reason behind it, read everything in detail?


Earthquake tremors were felt across North India including Delhi-NCR on Friday night. According to the National Center for Seismology, the earthquake was 6.1 and its epicenter was Amritsar in Punjab. Now the question is, do you know why earthquake occurs and how it is known. How does one know the magnitude of an earthquake?

Why does an earthquake occur?

There are 7 plates inside the earth, which rotate continuously. Where these plates collide more is called the zone fault line. Repeatedly hitting the corners of the plates turns. Plates break when more pressure is created. The downward energy finds its way out and the earthquake is followed by the disturbance.

Know what is the meaning of the center and intensity of an earthquake?

The epicenter of the earthquake is the location just below which the stirring in the plates emits geological energy. The earthquake vibrates more at this place. As the frequency of vibration decreases, its effect decreases. However, if there is an earthquake of 7 or more on the Richter scale, then the jolt intensifies in the vicinity of 40 km. But it also depends on whether the seismic frequency is upward or in scope. If the frequency of vibration is up then the lower area will be affected.

How is the intensity of an earthquake measured and what is the scale of measuring?

The landscape is examined with the Richter scale. This is called the Richter Magnitude Test Scale. Earthquakes are measured on a Richter scale from 1 to 9. Earthquake is measured from its epicenter. The intensity of the energy that comes out from within the earth during an earthquake is measured by it. The magnitude of earthquake tremors is estimated from this intensity.

How much devastation does an earthquake bring?

Richter scale bearing

0 to 1.9 shows only from the seismograph.

2 to 2.9 light vibration

3 to 3.9 if a truck passes near you, such an effect

4 to 4.9 windows can break and frames can fall on the walls.

5 to 5.9 furniture can move.

The foundation of 6 to 6.9 buildings can be cracked. Upper floors may suffer damage.

7 to 7.9 buildings collapse. Pipes burst inside the ground.

Large bridges including 8 to 8.9 buildings also collapse. Tsunami threat.

9 and more devastation than that, if someone is standing in the field, he will be seen waving the earth. Tsunami if the sea is near.
