On Tuesday, 3 February, residents across Bangladesh experienced two separate tremors within a single day, sparking renewed concerns over the country’s seismic vulnerability. The most significant quake occurred at 9:40 pm local time, originating in Minbu, Myanmar, and registering a magnitude of 5.9 on the Richter scale. The tremor was widely felt in Dhaka, Chittagong, and other parts of the country. Earlier in the day, several regions recorded a milder tremor, raising alert among seismologists and authorities.
Experts have noted that the fault line responsible for these quakes is highly active. Seismologists have cautioned that aftershocks and additional tremors could occur within the next 24 hours. Dr Mostafa Kamal Palash, a climate and weather researcher at the University of Saskatchewan, Canada, issued a warning on his verified Facebook account. Citing data from the United States Geological Survey (USGS), he stated that the recent major quake occurred at a depth of approximately 63 kilometres.
According to the European-Mediterranean Seismological Centre (EMSC), only twenty minutes after the 5.9-magnitude tremor, Minbu experienced another quake measuring 5.3. Earlier in the morning, a lighter tremor of magnitude 4.1 struck Kalaroa in Satkhira, affecting Dhaka and neighbouring districts.
Summary of Tuesday’s Earthquakes:
| Date & Time (BST) | Epicentre | Magnitude (Richter) | Depth (km) | Affected Areas |
|---|---|---|---|---|
| 3 Feb, Morning | Kalaroa, Satkhira | 4.1 | 10 | Dhaka and surrounding districts |
| 3 Feb, 21:40 | Minbu, Myanmar | 5.9 | 63 | Dhaka, Chittagong, Cox’s Bazar |
| 3 Feb, 21:51 | Minbu, Myanmar | 5.3 | 65 | Myanmar and border areas |
Seismologists emphasise that the region’s fault lines remain highly active. In 2024, the same fault line produced a powerful 7.5-magnitude earthquake, underlining the long-term seismic risk for the area. Both local and international experts are advising citizens to remain vigilant, especially in high-risk zones, and to take necessary safety precautions.
Official safety guidance includes seeking shelter in secure locations during tremors, avoiding high-rise buildings, and keeping an emergency kit ready. Authorities stress that remaining calm, aware, and prepared is essential, as public vigilance and readiness are critical to minimising casualties and damage in this seismically active region.
