Earlier, Sylhet was rattled by back-to-back earthquakes in May and June
A moderate earthquake of 5.6 magnitude on the Richter Scale struck Bangladesh early Friday.
The tremor was felt in several parts of the country including Dhaka and Chittagong at 12:28am. But no casualties were reported immediately.
According to a Bangladesh Meteorological Department (BMD) official, the quake's epicentre was in Myanmar’s Monywa, about 477km southeast of Dhaka.
Earlier, several buildings in Sylhet tilted and cracks developed as nearly a dozen tremors struck the city in May and June, prompting the authorities to launch a survey.
The successive earthquakes spread panic among locals, while experts anticipate a potential major quake occurring sometime.
In late May, the Sylhet City Corporation (SCC) authorities prepared a list of 25 under-risk buildings and markets in the city.
SCC Mayor Ariful Haque Chowdhury ordered that the buildings and markets under risk remain closed for 10 days. Residents of those buildings were also asked to move away elsewhere.
Moreover, several teams of experts were formed with teachers of Shahjalal University of Science & Technology (Sust) to assess the vulnerability of the city’s buildings.
Sylhet is located near the Dawki Fault, which is responsible for a number of devastating quakes for over a century, and most of the epicentres were near the city, according to the United States Geological Survey (USGS), which records earthquakes across the world.
On the other hand, Chittagong is vulnerable due to Plate Boundary fault 1, 2 and 3 in the Bay while Dhaka, with the Madhupur blind fault, is vulnerable, even in a mid-level tremor, because of its high population density and high-rise concrete structures.
