Information on earthquakes in and around Bangladesh is available for the last 250 years. The earthquake record suggests that since 1900 more than 100 moderate to large earthquakes occurred in Bangladesh, out of which more than 65 events occurred after 1960. This brings to light an increased frequency of earthquakes in the last 30 years. The increase of tremors is an indication of fresh tectonic activity or propagation of fractures from the adjacent seismic zones.
Before the coming of the Europeans, there was no definite record of earthquakes. Following is a chronology of important earthquakes from 1997.
