Twin Earthquakes Heighten Alert in Sylhet

In the early hours of Monday, residents across Sylhet and other parts of Bangladesh were shaken by two successive earthquakes, triggering widespread alarm. The tremors, occurring only seconds apart, caused temporary panic in homes, offices, and commercial centres, as people rushed to ensure their safety.

According to the United States Geological Survey (USGS), the first earthquake struck at 4:47:39 am local time on 5 January, registering a magnitude of 5.2 on the Richter scale. Merely thirteen seconds later, at 4:47:52 am, a second tremor followed, slightly stronger, measuring 5.4 on the same scale.

Both earthquakes originated in India’s Assam state. The initial tremor occurred near Dhing at a depth of 35 kilometres, while the second was recorded near Morigaon, close to Assam’s capital, Guwahati, at an approximate depth of 30 kilometres.

Dr. Mostafa Kamal Palash, a climate and seismology researcher at the University of Saskatchewan, Canada, cautioned via social media that the second quake, being of moderate intensity, could be followed by aftershocks within the next 48 hours. He added that these aftershocks might be felt in Bangladesh, particularly in northern and north-eastern districts along local fault lines.

The following table summarises the key details of the twin earthquakes:

In Bangladesh, Sylhet and other north-eastern regions experienced noticeable tremors, leaving many residents anxious about possible aftershocks. Seismologists have advised the public to remain in safe locations and avoid tall buildings until the situation stabilises.

Local authorities have issued emergency alerts, emphasising that both Assam and the adjoining districts of northern Bangladesh are seismically active zones. Citizens have been urged to maintain emergency plans, identify safe spots in homes and workplaces, and stay vigilant in the coming days.

Currently, the entire north-eastern region, including Sylhet, remains on high alert. While the intensity and frequency of potential aftershocks over the next 48 hours remain uncertain, authorities continue to caution residents to stay prepared and act prudently.
