Bangladesh is on the verge of a big earthquake, Dhaka is most at risk

The capital Dhaka is one of the most risky areas in the world for earthquakes. Although there has been talk of implementing various projects and schemes to reduce the risk of this densely populated city, most of it has not seen the light of day.

Citing a report by the Earth Observatory, BBC Bangla said in a report that Bangladesh is located at the junction of the three plates – India, Eurasia and Burma. Which can pose a risk of major earthquakes.

Every time there is a big earthquake, there is a lot of activity, which is kept under wraps until another big earthquake hits.

According to the report, multi-storied buildings stand in a small space on both sides of the narrow alleys of old Dhaka. There is no condition to see the sky between the two buildings facing each other.

People were terrified when an earthquake shook the region in the early hours of Friday (November 26). But none of them have enough space on the street below the building. The residents of old Dhaka are therefore scared during the earthquake, when the building collapses on them.

Experts said that such a multi-storey building in such a small area is extremely risky in case of earthquake or any other disaster.

Syed Humayun Akhter, a professor of geology at Dhaka University, told the media that large earthquakes usually occur every 100 years. The last major earthquakes were in 1822 and 1918 at Madhupur Fault. As such, Bangladesh is on the brink of another major earthquake. Dhaka is at the highest risk.

A joint survey by the Disaster Management Program (CDMP) and JICA in 2009 found that if an earthquake of magnitude seven or more was felt in Dhaka, 72,000 buildings in the city would collapse and 135,000 buildings would be damaged. 70 million tons of concrete will be made.

According to the Fire Service and Civil Defense, 8 percent of the roads in Dhaka city are narrow, so it will be difficult to carry out rescue operations in the event of an earthquake.

In addition, 80 per cent of the buildings have been redesigned, which is why it is feared that these unplanned buildings may collapse immediately during a major earthquake. At the same time, explosions in gas, electricity and water lines can lead to a terrible situation.

Earthquakes were felt in different parts of Bangladesh in 2015 due to the high magnitude earthquake in Nepal. At that time, a meeting of the National Disaster Management Council, chaired by Prime Minister Sheikh Hasina, decided to set up a ‘National Emergency Operations Center’. That decision has not yet been fully implemented.

The meeting also decided to set up a website called National Disaster Management Information System (NDMIS). It also did not see the face of light.

According to experts, the biggest weakness is not building buildings according to building codes and not taking any action by monitoring them.

Examination of multi-storied buildings in many elite areas, starting from crowded areas of Dhaka, revealed that most of them are not earthquake tolerant. In this case, it is necessary to identify the hazardous buildings and demolish them or repair them in an earthquake-tolerant manner, but no progress has been made in this regard.
