Earthquake tremors felt in Kolkata, Northeast; six people die in epicentre Bangladesh

Pakistan hit by strong 5.2-magnitude earthquake early morning, tremors felt in Afghanistan

Earthquake tremors were felt in West Bengal's Kolkata at 10:10 am and lasted for about 20 seconds as well across the Northeast, according to reports. An earthquake has been reported in Bangladesh with epicentre in Dhaka.

A 5.5-magnitude earthquake struck near Narsingdi, Bangladesh at 10:08 am, according to United States Geological Survey, killing at least six people and leaving dozens injured. Buildings in the country's capital, Dhaka, swayed in the temblor, sending panicked residents into the streets, reported AP.

The quake hit at 10:38 a.m., with the epicenter in the Ghorashal area in Narsingdi district, about 25 kilometers (16 miles) from Dhaka. The U.S. Geological Survey said it had a depth of 10 kilometers (6 miles).

Dhaka-based DBC Television reported that at least six people died in Bangladesh's capital; three from the collapse of a building roof and a wall, and three pedestrians when building railings fell on them in Dhaka.

Social media users shared visuals of objects shaking due the impact of the earthquake on social media, sharing screenshot of magnitude felt in their location.

Tremors were widely felt in Dhaka around 10:40 am and were also reported in parts of India, including West Bengal and adjoining north east India, reported ANI.

There have been no reports of casualties or damage so far, and authorities have not issued any advisory.

Last month, in October, an earthquake of magnitude 3.4 struck Bangladesh, the National Centre for Seismology (NCS) reported.

Shallow earthquakes like this one tend to cause stronger shaking because seismic waves travel a shorter distance to the surface. According to global seismic data, an earthquake occurs somewhere in the world roughly every 30 seconds, although most are too weak to be detected.

The Daily Star, citing USGS figures, reported that a magnitude 4.0 earthquake releases energy equivalent to about 6 tons of TNT, while a magnitude 5.0 earthquake corresponds to around 200 tons. The energy rises sharply with each increase in magnitude: a 7.0 quake equals nearly 199,000 tons of TNT, and a 9.0 quake releases about 99 million tons, comparable to roughly 25,000 nuclear bombs.

Bangladesh sits on a highly active junction of three tectonic plates--the Indian, Eurasian and Burma plates. The Indian plate moves northeast at about 6 cm per year, while the Eurasian plate moves northward at around 2 cm per year over it.

The country lies close to several major fault lines, including the Bogura fault, Tripura fault, Shillong Plateau, Dauki fault and Assam fault, making it part of 13 earthquake-prone zones. Areas such as Chattogram, the Chattogram Hill Tracts and Jaintiapur in Sylhet fall in the highest-risk category.

Dhaka, with more than 30,000 people per square kilometre, is one of the densest cities in the world and has been identified as one of the 20 most earthquake-vulnerable cities globally, according to The Daily Star.
