Bangladesh lies in a highly sensitive seismic zone where three major tectonic plates meet, the Indian, Eurasian and Burma plates. The Indian plate is slowly moving northeast at about six centimetres per year, while the Eurasian plate is moving north at around two centimetres per year.
There are five major fault zones in and around Bangladesh: the Bogura fault zone, Tripura fault zone, Shillong Plateau, Dauki fault zone and Assam fault zone. Because of this, the country has at least 13 earthquake-prone areas.
Regions such as Chattogram, the Chattogram Hill Tracts and Jaintiapur in Sylhet are considered extreme risk zones. Dhaka, one of the most densely populated cities in the world, has also been marked as one of the 20 cities most vulnerable to earthquakes globally, according to reports.
Authorities in the region continue to monitor seismic activity and have urged people to remain alert, calm and follow safety guidelines.
