With Saturday’s 5.5 magnitude tremor which shook Dhaka and nearby areas, Bangladesh has witnessed six incidents of earthquakes over magnitude 5 since the beginning of 2023.
Earlier on October 2, the country experienced a 5.4 magnitude earthquake originating from Sherpur.
On September 11, Sylhet was struck by an earthquake measuring 5 in magnitude.
The country felt the impact of a 5.0 magnitude earthquake originating from Golapganj in Sylhet, affecting Dhaka and other districts on June 16.
The first seismic activity recorded this year was on January 23 with a 5.1 magnitude earthquake originating in Sylhet.
According to experts, mild to moderate earthquakes are felt in the country due to the opposing movement of the Burmese Plate and the Indian Plate. They said that there is a significant accumulation of energy at the junction of these two plates, which is seeking a way to be released, causing frequent earthquakes.
Experts highlight that Bangladesh is located in an earthquake-prone zone. The amount of energy accumulated beneath it suggests the potential for a major earthquake in the country. They, however, said that Chattogram Hill Tracts, Dhaka, Rangpur, Mymensingh, Netrakona and Dinajpur regions are particularly vulnerable to earthquakes.
Aside from Bangladesh, areas such as India’s Meghalaya, Assam, Manipur, Mizoram, and those near the Myanmar border are also vulnerable to face significant damage from an earthquake with a magnitude exceeding 7 on the Richter scale.
