Strong tremors of an earthquake have been felt in Delhi-NCR. People in Ghaziabad, Noida, and Delhi felt the tremors of the earthquake.

Why does an earthquake occur?

There are 7 plates inside the Earth, which keep rotating continuously. The zone where these plates collide is called a fault line. Due to repeated collisions, the corners of the plates bend. When more pressure is created, the plates start breaking. The energy below finds a way to come out, and after the disturbance, an earthquake occurs.

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

The center of an earthquake is the place just below which geological energy is released due to movement in the plates. The vibration of the earthquake is greater at this place. As the frequency of vibration goes away, its effect decreases. Still, if there is an earthquake of intensity 7 or more on the Richter scale, then the tremor is strong within a 40 km radius. But it also depends on whether the seismic frequency is on top or in the range. If the frequency of vibration is higher, then less area will be affected.

How is the intensity of an earthquake measured, and what is the scale to measure it?

Earthquakes are measured using the Richter scale. It is called the Richter Magnitude Test Scale. On the Richter scale, earthquakes are measured on a basis of 1 to 9. Earthquakes are measured from its center i.e. the epicenter. The intensity of the energy released from within the Earth during an earthquake is measured by this. The severity of the earthquake shock is estimated from this intensity.
