Bangladesh on Edge: Experts Warn of Looming Earthquake Disaster

The country has experienced two earthquakes within seven days, with over 50 mild to strong tremors recorded around Bangladesh in the last 90 days. Over the past 15 years, more than 150 earthquakes of varying magnitudes have occurred. Experts warn that these tremors could be precursors to a major earthquake.

Dhaka ranks among the world's 20 most earthquake-prone cities. A significant earthquake in Bangladesh could result in substantial damage, yet no government has taken measures to mitigate such risks.

Experts highlight that these minor tremors indicate the potential for a larger earthquake, with Bangladesh's geographical position adding to its vulnerability. Regions like Sylhet, Rangpur, Mymensingh, and Chattogram are at higher risk of severe damage than Dhaka.

Recently, a 7.1 magnitude earthquake in Tibet claimed over a hundred lives, with tremors felt in Bangladesh, Nepal, and India. The region's location on major tectonic fault lines causes frequent seismic activity.

The US Geological Survey (USGS) notes that Bangladesh lies in an active seismic zone, with recent tremors signaling the possibility of a stronger earthquake. Dhaka is one of the most vulnerable cities globally to earthquakes. The last major earthquake in Bangladesh was in 1918, with its epicenter within the country. A 6.7 magnitude quake in 2016 caused panic-related fatalities. With no major earthquakes in the past 75 years, experts fear a significant one is imminent.

Bangladesh's tectonic positioning, with the Indian and Myanmar plates running through it, has accumulated energy over centuries. A sudden release could result in an earthquake of 8 to 9 magnitudes, potentially devastating Dhaka with significant casualties and destruction. A joint survey by BUET and the government estimates that a 7.5 magnitude earthquake could collapse 72,000 buildings in Dhaka, creating 70 million tons of concrete debris.

Dr. Md. Zillur Rahman, Dean of the Faculty of Earth and Environmental Sciences at Dhaka University, stresses the risk to areas like Mymensingh, Rangpur, Sylhet, Chattogram, and Dhaka, particularly due to the vulnerability of Dhaka's buildings.

Prof. Mehedi Ahmed Ansari from BUET's Civil Engineering Department explains that Bangladesh is situated at the confluence of three tectonic plates, all active with an annual movement of 5 centimeters. This movement increases the risk of seismic activity.

He also highlights the inadequacy of merely having equipment for fire service and civil defense without addressing structural vulnerabilities in buildings. The unplanned gas and electricity lines in Dhaka further escalate the potential for earthquake damage.
