Bangladesh has been classified into three earthquake risk zones, with Zone-1 marking the highest risk areas, mainly in the northern and southeastern regions. Districts in Sylhet and Mymensingh divisions, parts of Tangail, Gazipur, Narsingdi, Kishoreganj, Brahmanbaria, Khagrachhari, and Rangamati fall under this category. The lowest-risk Zone-3 includes Khulna, Jessore, Barishal, and Patuakhali. Historical data shows at least five major tremors between 1976 and 2015, mostly originating from Sylhet, Moulvibazar, Rangamati, Bandarban, and Cox’s Bazar. Experts warn that Dhaka, with around 2.1 million buildings, faces severe danger due to poor compliance with building codes. Fault lines such as the Dawki and Madhupur faults, along with several plate boundaries, make the region highly vulnerable. Specialists emphasize strengthening earthquake preparedness, enforcing construction standards, and investing in early warning systems to mitigate potential disasters.
