At least ten dead and more than 100 injured following Magnitude 5.5 Earthquake in central Bangladesh.

The United States Geological Survey recorded a Magnitude 5.5 Earthquake at a depth of about 10 km, roughly 30 km to the northeast of the Bangladeshi capital, Dhaka, slightly after 10.35 local time (slightly after 4.35 am GMT) on Saturday 22 November 2025. At least ten people, including at least one child, have died as a result of the event, with more than 100 injured. Most of those killed or injured appear to have been struck by debris falling from buildings in densely populated urban areas; three people were reportedly killed in a single incident when they were struck by a falling balcony. The event was felt across Bangladesh, as well as neighbouring areas of India.

Earthquake activity in northern Bangladesh is influenced by the uplift of the Tibetan Plateau, due to the impact of India into Eurasia to the south. The Indian Plate is moving northwards at a rate of 5 cm per year, causing it to impact into Eurasia, which is also moving northward, but only at a rate of 2 cm per year. The collision of the Indian and Eurasian plates has led to the formation of the Himalayan Mountains, the Tibetan Plateau, and the mountains of southwest China, Central Asia and the Hindu Kush.

Eastern Bangladesh is also in an area particularly prone to Earthquakes; much of nearby Myanmar lies on the Burma Plate, a small tectonic plate caught between  the Eurasian Plate to the northeast, the Indian Plate to the west and southwest and the Sunda Plate to the southeast. As these larger plates move together the Burma Plate is being squeezed and fractured, with a major fault line, the Kabaw Fault, having formed across much of the north of the country, along which the Burma Plate is slowly splitting. Most Earthquakes in the region are caused by movement on this fault.

The central part of Bangladesh is potentially affected by both tectonic systems, but is rather less prone to earthquake events, with only six Earthquakes of Magnitude 5.5 or greater since 1950. This may help to explain the level of deaths and injuries associated with this event, although building safety has been a long standing political issue in Bangladesh, marked by events such as the Tazreen Factory Fire in 2012, in which at least 112 people died in a fire at a nine-story factory building with insufficient fire escapes, and the Rana Plaza collapse in 2013, in which an eight story commercial building collapsed, killing 1134 people. Since 2013, the Bangladesh Accord on Fire and Building Safety2018 Transition Key Accord, and most recently the Readymade Sustainability Council, have sort to get international garment manufacturing companies operating in Bangladesh to sign up to fire and building safety protocols, but there remains little general building regulation.
