Dhaka, Bangladesh — An earthquake measuring 4.1 on the Richter scale struck Bangladesh in the early hours of Thursday, the National Center for Seismology (NCS) reported on X. The agency said the quake occurred at 5:44 AM Indian Standard Time (IST) on December 4, 2025, at a depth of 30 kilometres. The reported epicentre coordinates were 23.95 N, 90.72 E.
The NCS post read: EQ of M: 4.1, On: 04/12/2025 05:44:45 IST, Lat: 23.95 N, Long: 90.72 E, Depth: 30 Km, Location: Bangladesh.
Authorities and seismologists note that shallow earthquakes, like this one at 30 km, can produce stronger ground shaking near the surface than deeper events because seismic waves travel a shorter distance before reaching populated areas.
Bangladesh lies at the junction of the Indian, Eurasian and Burma plates. The Indian plate is moving northeast at roughly 6 cm per year while the Eurasian plate moves north at about 2 cm per year over the Indian plate. Five major fault zones affect the region: the Bogura, Tripura, Shillong Plateau, Dauki and Assam fault zones. Overall, the country contains 13 areas identified as earthquake-prone.
Some regions are considered especially vulnerable, including Chattogram, the Chattogram Hill Tracts and Jaintiapur in Sylhet. In November, a stronger 5.5-magnitude quake damaged buildings in Dhaka and elsewhere; on November 21 a rooftop railing on an eight-storey building in Armanitola collapsed, killing at least three people and injuring ten, local reports said.
Dhaka is among the world’s most densely populated cities — in 2022 it was recorded with about 30,093 residents per square kilometre — a factor that increases the potential human toll and infrastructure risk from future quakes.
