Why do earthquakes occur?
There are seven tectonic plates inside the earth. These plates keep rotating continuously. When these plates collide with each other, they rub. When they climb over each other or move away from them, the ground starts shaking. This is called earthquake. Richter scale is used to measure earthquakes. Which is called Richter Magnitude Scale. The Richter magnitude scale ranges from 1 to 9.
The intensity of an earthquake is measured from its center i.e. epicenter. That means the energy coming out from that center is measured on this scale. 1 means low intensity energy is coming out. 9 means the highest. Very frightening and destructive wave. They become weaker as they move away. If the intensity is 7 on the Richter scale, then there is a strong shock within a radius of 40 kilometers around it.
