Earthquake – A mild earthquake measuring 3.3 on the Richter scale was recorded in Bangladesh during the early hours of Monday, according to official data released by the National Centre for Seismology. The tremor occurred at 4:50 am IST and originated at a depth of 45 kilometres beneath the surface.

Details Confirmed by Seismology Officials

In a formal update shared through its official communication channels, the National Centre for Seismology stated that the quake’s epicentre was located at latitude 25.08 degrees North and longitude 92.03 degrees East. The agency confirmed that the event took place on February 9, 2026.

The depth of 45 kilometres indicates that the tremor originated well below the Earth’s surface, which can sometimes reduce the intensity felt at ground level. There were no immediate reports of injuries or property damage following the quake.

This is the second low-intensity earthquake reported in Bangladesh this month. On February 1, a tremor of magnitude 3.0 was also recorded in the region.

Tectonic Setting Raises Long-Term Concerns

Bangladesh’s geographical position makes it particularly vulnerable to seismic disturbances. The country lies at the meeting point of three major tectonic plates — the Indian Plate, the Eurasian Plate, and the Burma Plate. These plates are in constant motion, building stress along fault lines that occasionally release energy in the form of earthquakes.

Scientific assessments indicate that the Indian Plate continues to move northeast at an approximate rate of six centimetres per year. Meanwhile, the Eurasian Plate shifts northward at around two centimetres annually. The interaction among these plates creates persistent geological pressure beneath the region.

Multiple Fault Lines Across the Country

Several active fault systems run through and around Bangladesh, increasing the probability of moderate to strong seismic events. Key fault zones include the Bogura fault, the Tripura fault, the Dauki fault, the Assam fault, and the Shillong Plateau region. Experts classify the country into 13 earthquake-prone zones based on seismic risk assessment.

Among the most vulnerable regions are Chattogram, the Chattogram Hill Tracts, and Jaintiapur in the Sylhet area. These zones are considered highly sensitive due to their proximity to major tectonic boundaries.

Dhaka Identified as Highly Vulnerable

The capital city, Dhaka, remains a point of significant concern for disaster management authorities. With a population density exceeding 30,000 people per square kilometre, it is one of the most densely populated urban centres in the world. According to earlier reports published by The Daily Star following a magnitude 4.1 earthquake in Dhaka on December 4, 2025, experts have listed the city among the 20 most earthquake-vulnerable cities globally.

Urban congestion, unplanned construction, and limited open spaces contribute to the risks associated with a potential high-magnitude earthquake. Specialists have repeatedly highlighted the need for structural safety audits, enforcement of building codes, and enhanced public awareness campaigns.

Preparedness and Technology Seen as Key

Seismologists and disaster response authorities stress that preparedness remains the most effective tool in minimizing casualties and infrastructure damage. Modern early warning systems, improved construction standards, and regular emergency drills are viewed as essential measures for a country situated in an active seismic belt.

While Monday’s tremor was relatively minor and caused no immediate disruption, it serves as a reminder of the geological forces beneath the region. Authorities continue to monitor seismic activity closely and encourage residents to remain informed about safety guidelines.
