Earthquake occurred in Delhi on Sunday. The earthquake occurred at 4:19 minutes 14 seconds after noon. However, earthquake tremors were not felt. The intensity of the earthquake was measured at 2 on the Richter scale. At the same time, its depth was 5 km. The epicenter of the earthquake was West Delhi.
Why do earthquakes occur?
There are 7 plates inside the Earth, which keep rotating continuously. The zone where these plates collide is called fault line. The corners of the plates bend due to repeated collisions. When too much pressure builds up, the plates start breaking. The energy below finds a way out and after the disturbance an earthquake occurs.
Know what is the meaning of the center and intensity of earthquake?
The epicenter of an earthquake is the place just below which geological energy is released due to movement in the plates. Earthquake vibrations are more severe at this place. As the frequency of vibration increases, its effect decreases. Still, if there is an earthquake with a magnitude of 7 or more on the Richter scale, then the shock is strong within a radius of 40 km. But it also depends on whether the seismic frequency is upward or downward. If the frequency of vibration is higher then less area will be affected.
