Panic spread in Chamoli, Uttarakhand after earthquake tremors were felt late Friday night. People came out of their homes and shops and stood on the road. Its intensity is being reported as 3.3 on the Richter scale.
According to the National Center for Seismology (NCS), an earthquake of 3.3 magnitude occurred in Chamoli district of Uttarakhand. Which was at a depth of 10 kilometers in the ground.
Earlier on July 8, an earthquake of 3.2 magnitude on the Richter scale occurred in Uttarkashi district of Uttarakhand. According to NCS, this earthquake occurred at a depth of 5 kilometers at 1:07 pm.
Why does earthquake occur?
There are 7 plates inside the earth, which keep rotating continuously. The zone where these plates collide more is called fault line. Due to repeated collision, the corners of the plates bend. When more pressure is built up, 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 epicenter and intensity of an earthquake?
The epicenter of an earthquake is the place just below which geological energy is released due to the movement of plates. The earthquake vibration is more at this place. As the frequency of vibration goes away, its effect decreases. Still, if there is an earthquake with an intensity of 7 or more on the Richter scale, then the tremor is strong in the surrounding 40 km radius. But it also depends on whether the seismic frequency is upwards or in the range. If the frequency of vibration is upwards, then less area will be affected.
How is the intensity of an earthquake measured and what is the scale to measure it?
Earthquake is tested by Richter scale. It is called Richter Magnitude Test Scale. On the Richter scale, earthquake is measured on the basis of 1 to 9. Earthquake is measured from its center i.e. epicenter. The intensity of the energy released from within the earth during an earthquake is measured by this. The intensity of the earthquake is judged by its magnitude.
