Bangladesh 5. 5-magnitude earthquake – what we know so far

A powerful earthquake measuring 5.5 on the Richter scale struck Bangladesh near its capital, Dhaka, on Friday morning at 10:38 am local time. The tremors lasted for about 26 seconds, causing panic among residents and leading to significant structural damage. Dhaka resident Shadman Sakif Islam described the experience as unlike anything he’d felt before — starting with small ripples in his coffee and quickly escalating to intense shaking that made furniture move wildly. He said it felt like riding massive waves on a boat, leaving him frozen for several seconds, completely unsure of what was happening. The epicenter of this quake was located in the Madhabdi district of Narsingdi, a city roughly 33 kilometers northeast of Dhaka. Narsingdi is well-known for its textile and garment industries, which may have faced operational disruptions due to the quake. The tremors were so strong they were felt as far as Kolkata in India, over 325 kilometers away, although no casualties have been reported there. In Dhaka itself, numerous buildings suffered damage, some of which led to tragic fatalities. According to official government reports, at least five people lost their lives in the earthquake, with around 100 others injured. However, some local media outlets like DBC Television have suggested a higher death toll, reporting six fatalities within Dhaka alone. These deaths included three individuals killed when a building’s roof and wall collapsed, and three pedestrians struck by falling railings on the streets. The government is still verifying casualty numbers as rescue and recovery operations continue. Earthquakes are not very common in Bangladesh despite its proximity to the meeting point of three major tectonic plates: the Indian, Eurasian, and Burmese plates. This geological setting makes the region susceptible to seismic activity, yet large quakes are rare. The last significant quake of similar magnitude was in 2023 near Sylhet, in northeastern Bangladesh, which measured 5.8 but caused no major damage or casualties. In 2021, a 6.1 magnitude quake struck near the India-Myanmar border, with tremors felt in Bangladesh’s Chittagong and Cox’s Bazar regions, but again, no confirmed deaths were reported within Bangladesh. Seismologists note that magnitudes are measured on a logarithmic scale, meaning each whole number increase equals a tenfold increase in the quake’s intensity. Therefore, while a 5.5 magnitude quake might seem moderate, its proximity to a densely populated city like Dhaka amplified its destructive potential. Social media was flooded with videos showing buildings swaying and residents evacuating their homes in panic. Experts say this quake is one of the strongest Bangladesh has experienced in recent years, urging authorities to review disaster preparedness and response strategies. The situation remains fluid, with emergency teams assessing structural integrity across the city and providing aid to those affected. Dhaka’s residents are still shaken but trying to return to normal life amid ongoing aftershocks. This incident has raised urgent questions about building safety standards in Dhaka and the need for better public awareness on how to respond during such natural disasters. For a country not frequently hit by earthquakes, the event serves as a grim reminder of the latent seismic risks that exist beneath the surface.
