Mild tremors were felt in Andaman and Nicobar Islands on Monday. According to the National Center for Seismology, earthquake intensity on the Richter scale has been measured at 4.1. The epicentre of the earthquake is believed to be the predecessor of Campbell Bay.
Let us know that earlier on March 21, earthquake tremors were felt in Mokokchung, Nagaland. The quake intensity here was 4.2 on the Richter scale. The quake’s epicentre was 77 km east of Mokochung. On 6 March in the same month, earthquake tremors were felt in Ladakh. The earthquake intensity here was measured at 3.6.
Know which earthquakes are dangerous
Explain that earthquakes with a magnitude usually up to 5 on the Richter scale are not dangerous, but it depends on the area’s structure. An earthquake of magnitude five can also be hazardous if the quake is on the river banks, and there are tall buildings built without seismic techniques. If there is an earthquake of magnitude seven or above on the Richter scale, then the jolt intensifies in the vicinity of 40 km. But it also depends on whether the seismic frequency is upward or within the radius. If the frequency of vibration is up, then the lower area will be affected.
How to avoid earthquake
- Cover your head with anything. If nothing is there, cover the head with your hand so that serious injuries do not occur.
- If you are on the bottom floor, then cover the head and come out into the ground.
- If you are in tall buildings, then reach a safe place like a corner, door, or under a strong table or plinth covering the head and wait for the shaking to stop.
- Come down the stairs and go towards the open ground.
