Bangladesh is one of the most tectonically active regions in the world. Bangladesh is facing a high risk of moderate to strong earthquakes that may result in widespread damage. It sits where three tectonic plates meet: the Indian Plate, the Eurasian Plate, and the Burmese Plate. Bangladesh is located close to the two subduction zones created by two tectonic plates: the Indian plate and the Eurasian plate. The capital city Dhaka is vulnerable to the earthquake as the country is in an active region. Bangladesh is extremely vulnerable to seismic activity.
There are many active faults along this boundary, such as the enormous Dauki fault that borders northern Bangladesh. According to a seismic zoning map prepared by
the BUET, 43 per cent areas in Bangladesh are rated high risk, 41 per cent moderate and 16 percent low . divides the country into three earthquake vulnerability zones. Panchagarh, Rangpur, Gaibandha, Kurigram,Jamalpur, Sherpur, Mymensingh, Netrakona, Sunamganj, Kishoreganj, Moulvibazar, Sylhet, Habiganj and Brahmanbaria are placed in the highest risk zone.
Seven major earthquakes struck Bangladesh during the last 150 years and only two had the epicentre within the country. Based on the epicentres of earlier earthquakes, Dhaka has crossed 130 years; Chittagong has crossed 250 years and Sylhet about 100 years, which now raises the prospect of a major earthquake striking Bangladesh

Historical Eartquaqe in Bangladesh
Since 1900 more than 100 moderate to large earthquakes occurred in Bangladesh, 65 events occurred after 1960. This increase in earthquake activity is an indication of fresh tectonic activity or propagation of fractures from the adjacent seismic zones
