Nowadays we hear a lot of news from the earthquake. Recently, there was a severe earthquake in Nepal, in which a lot of people had gone.

Today countries like Pakistan too have received some setbacks and this is a big disaster. It is important to know what is an earthquake and what are it's types followed by the main theme of how to protect yourself from an earthquake.

An earthquake is such a natural disaster that nobody gets stressed. This natural disaster hits any place without saying that, with the loss of huge public wealth, it creates havoc all the way. 

Earthquake is a sudden vibration in the lower surface of the Earth, causing compression through the same velocities that are generated due to the imbalance of gases in the layers of the Earth's surface.

And the movement starts on the top surface of the surface. At the same time according to the velocity of the intensity of the velocities, the upper surface of the earth begins to erupt and gradually subsides.

Sometimes the intensity of the earthquake is so high that the building collapses. The reservoirs are inundated and sometimes even tsunamis and landslides cause earthquakes. 

Earthquakes are counted in the reactor. Two-three reactors are considered normal whereas, seven and above reactors are considered very severe and dangerous earthquakes, which are in the form of heavy destruction. 

 Wave is the main reason for the earthquake. The formation of waves in the lower surface of the surface, the effect of those waves is seen on the upper surface. In the same way, the intensity of the waves shows the effect of the upcoming earthquake.

Primary or P waves - The earliest start of an earthquake in which there is no damage. It is usually a zero to three reactors generated on the earth. 

Secondary Wave (Secondary, S or Shear Waves) - Secondary wave is the second stage in which a person can work well if he works intelligently. 

From four to seven reactors in which the same kind of shaking starts like furniture, vehicle house and other similar and cracks in the walls, the windows of houses start moving. 

L or Surface Waves - The most dangerous wave of an earthquake, which causes great devastation and kills everything. Many times, their form is so frightening that only destruction is seen around. Having more than seven reactors, it crosses to eight, nine, ten reactors, in which- 

Big buildings and buildings and bridges fall, floods, even tsunamis. There is absolutely no chance of saving anything in it. 

How to protect from earthquakes? 

If you work by planning, then any crisis can be avoided. Similarly, safety and caution can be maintained during and after an earthquake. 

As soon as the earthquake strikes, feel light-hearted and stand on the Bahar Road or open ground from the house, office or closed building.

Remove the gas cylinder and electric main switch in the house. Neither drive a vehicle nor travel in vehicles. 

Stand anywhere in a safe and covered place.

Do not stand near any deep place, well, pond, river, sea, and weak and old house.

Before the earthquake, also pay attention to the prediction and natural signs made by scientists, taking safety and precautions and avoiding earthquakes.
