Speaking to ANI, Mishra said "It occurred in the longest fault in Myanmar, Sagaing Fault. Its length is 1200 km. This fault has generated several earthquakes in the past of magnitude more than 7. This is not the first earthquake with magnitude 7."

Further, he stated that the earthquake occurred at a depth which was of shallow range between 20 to 30 kilometres.

Why Myanmar is vulnerable to deadly seismic events

"This is a very highly seismic-prone zone where there are greater chances for an earthquake to take place. Its depth was in shallow range, between 20-30 km. When the main shock occurred at 11.50 am, around 12 noon, the earthquake generated an aftershock of magnitude 7. Between 12.30 pm and 1 pm, another aftershock of magnitude 5 occurred. There was an aftershock of 4.9, too. It means that three aftershocks have already occurred," the Director further added.

He also stated that damage occurred in Bangkok, the capital city of Thailand, due to the rupture of the Sagaing fault heading there.

Further, he added that the number of aftershocks that occurred will be revealed only after 24 hours.

"The damage in Bangkok city of Thailand occurred because the Sagaing Fault's rupture headed towards Bangkok, and several people felt the tremors there. It is the alluvial belt of Bangkok where the chances of liquefaction are quite high. Buildings were not able to withstand it, so there was damage there. Within 24 hours, we will get to know how many aftershocks came," he stated.
