Concerning Surge in Earthquakes Observed in February

In a notable pattern of seismic activity, Bangladesh has experienced eight earthquakes in the first 25 days of February. The most recent tremor occurred on Wednesday night, registering a magnitude of 4.1. Experts have cautioned that the frequent occurrence of small and moderate tremors may signal underlying geological instability, warranting increased vigilance.

Seismologists have observed a rising trend in minor and moderate earthquakes both within Bangladesh and in neighbouring regions. While these tremors are not immediately destructive, they could indicate the potential for a larger seismic event in the future, according to geological analyses.

A summary of February’s earthquakes is presented in the following table:

According to the Bangladesh Meteorological Department, the 25 February tremor originated in Myanmar’s Sagaing region. Data from the Euro-Mediterranean Seismological Centre (EMSC) indicate that the epicentre was located at 23.031°N latitude and 94.744°E longitude, with a depth of approximately 101 kilometres. The earthquake occurred roughly 110 kilometres north-northwest of the city of Monywa and 76 kilometres southeast of Mawlaik. Its considerable depth prevented significant damage, though a brief light tremor was perceptible in Dhaka.

This surge follows the major earthquake of 21 November last year, which registered a magnitude of 5.7. That event resulted in at least 10 fatalities, over 600 injuries, and substantial structural damage across the country, including the capital.

Seismic experts emphasise that the current frequency of tremors may serve as a precursor to larger earthquakes. They have urged heightened seismic awareness, public education, and preparedness across all regions of Bangladesh to mitigate potential risks.
