According to the National Center for Seismology, a 4.3 magnitude earthquake struck the eastern Sikkim district on Sunday night. The earthquake occurred at 9:50 pm. The epicenter of the earthquake was located at 27.25 degrees north latitude and 88.77 degrees east longitude, about 18 km from the state capital, Gangtok.

Locals said the tremors were felt in the districts of Darjeeling and Kalimpong in the northern parts of neighboring West Bengal. According to initial reports, there were no reports of loss of life or property due to the earthquake, official sources said.

How does an earthquake happen?
The main reason for the occurrence of earthquakes is the collision of plates within the earth. There are seven plates within the earth that are constantly rotating. When these plates collide somewhere, a fault line zone forms and the corners of the surface twist. Due to the twisting of the corners of the surface, the pressure builds up there and the plates begin to break. Due to the rupture of these plates, the energy inside finds a way out, so the earth shakes and we consider it an earthquake.

earthquake intensity
Earthquakes with a magnitude less than 2.0 on the Richter scale are classified as micro and these earthquakes are not felt. Every day 8,000 earthquakes of the micro category on the Richter scale are recorded around the world. Similarly, earthquakes of magnitude 2.0 to 2.9 remain in the minor category. Normally, we don’t even feel about 1,000 such earthquakes every day. Very mild category earthquakes of magnitude 3.0 to 3.9 are recorded 49,000 times in a year. They feel, but they hardly hurt.

Mild category earthquakes with a magnitude of 4.0 to 4.9 are recorded on the Richter scale approximately 6,200 times a year worldwide. These tremors can be felt and seen by moving household items. However, they cause negligible damage.
