On 21 November 2025, at 10:38:26 BST (UTC+6), a moment magnitude 5.4 earthquake struck near Dhaka, Bangladesh, as the result of reverse faulting at shallow depth within the Indian plate, followed by at least three aftershocks. At least 10 people died and nearly 630 others suffered injuries. It was the deadliest earthquake to strike the country in over two decades. [2]
Much of Bangladesh sits in the Indian and Eurasian plate. The Indian plate converges with Eurasian at a rate of approximately 46 mm/yr towards the north-northeast. The broad convergence between these two plates has resulted in the uplift of the Himalayas, the world's tallest mountain range. The preliminary focal mechanism of the earthquake suggests strike slip faulting, and thus an intraplate source within the upper Eurasian plate or the underlying Indian plate, rather than occurring on the thrust interface plate boundary between the two. This region has experienced relatively moderate seismicity in the past, with 18 earthquakes of the magnitude of 5 or greater over the past 35 years. The largest of these was an earthquake of a magnitude of 6.1 in November 1980. [3]
The earthquake struck at 10:38:26 BST (04:38:26 UTC). Its epicentre was near Madhabdi, 14 kilometres (8.7 miles) southwest from Narsingdi, with a depth of 10 kilometres (6.2 miles). The quake was measured at Mw 5.4 by the United States Geological Survey (USGS), [4] and ML 5.7 by the Bangladesh Meteorological Department (BMD). [5] The shaking lasted for 26 seconds, according to the BMD. [6] Tremors were also felt in Kolkata and eastern states of India. [6] [7] The USGS estimated that more than 10 million people in Dhaka and 300,000 people in Narsingdi felt strong shaking. [8]
According to Bangladeshi earthquake expert Humayun Akhtar, the earthquake was the strongest in the recent history of Bangladesh. [5] According to Rubayet Kabir, a top official at the BMD's Earthquake Observation and Research Centre, the earthquake was strongest in the country in the last 30 years, and released the same amount of energy as the atomic bombs dropped on Hiroshima and Nagasaki. [9]
At least three aftershocks were detected after the earthquake on 22 November. The first one struck at 10:36:12 BST of ML 3.3, with the epicentre in Palash, Narsingdi, the second one in 6:06:04 BST of ML 3.7 with the epicentre in Badda, Dhaka, and the third one in 6:06:05 BST of ML 4.3 with the epicentre in Narsingdi.

Many people evacuated buildings during and after the earthquake. [14] Several buildings reportedly sustained cracks, had tilted or were damaged by fires throughout the country. [1] [15] According to the Dhaka District Administration, at least 300 buildings sustained damage in Dhaka, while the Rajdhani Unnayan Kartripakkha (RAJUK) put the number at over 50, including many buildings that had tilted. [16] [17] In the immediate aftermath of the earthquake, seven power stations were shut down and electricity generation was disrupted, resulting in rolling blackouts nationwide. [18] [19] Ground ruptures were also observed in Palash and Ghorashal, near the epicentre. [20]
At least 10 deaths were reported, including five in Narsingdi District, four in Dhaka District, and one in Narayanganj District, [21] with 629 others injured across Bangladesh. Three people died and injuries were reported in the Koshaituli area of Old Dhaka after a brick-made railing collapsed. [22] Another roof collapse left three people injured in Gabtali. [23] At least 22 students of Dhaka University (DU) were also injured, including some who jumped off their residence hall. [24] At least 10 of DU's dormitories sustained cracks. [25] More than 400 people were injured while fleeing out of buildings, a four-storey building collapsed and a hospital was damaged in Gazipur District. [26] A newborn child was killed and two others were injured after a wall collapsed on them in Narayanganj. [27] Six people were injured by collapsed walls in Araihazar, Narayanganj. [28] Over 100 people were injured in Narsingdi District, directly at the epicenter, and many buildings were damaged. [29] [30] At least 85 workers at the Comilla Export Processing Zone were injured or fainted as a result of panic. [31] Reports of damage at the Chief Adviser's Office also arrived at the fire service, but no significant effects were found after inspection. [32] Major cracks occurred in the front section of the National Institute of Traumatology and Orthopedic Rehabilitation. [33]
In Rajshahi, the second and third floors of the Sher-e-Bangla hall of Rajshahi University tilted due to the shaking. Similarly, in Chittagong, a six-story building leaned against another six-story building after the earthquake. [34]
A test match between Bangladesh and Ireland cricket teams at Sher-e-Bangla National Cricket Stadium was also halted for three minutes due to the earthquake. Spectators panicked and rushed in all directions, while the Irish cricketers moved to the ground for safety. [35] [36]
The second and third aftershocks also resulted in mass evacuation in several places. [37] At least six students of DU were injured while rushing out of their residential halls. [38]
Public institutions like Dhaka University, Jagannath University and Dhaka Medical College Hospital suspended academic activities in various terms after the aftershocks. [39] [40] [41] [42] Many non-governmental educational institutions switched to online learning. [40] Some students of DU slept outside the residence of the vice-chancellor, fearing the aftershocks. [43] Petrobangla was instructed by the Ministry of Power, Energy and Mineral Resources to suspend oil and gas exploration drilling in the country for 48 hours starting on 23 November. [44]
Chief adviser Muhammad Yunus held an emergency meeting of earthquake experts, researchers and university professors on 24 November 2025, which concluded with the decision to establish a taskforce on earthquake preparedness. [45] [46]
Structures shook and many people evacuated buildings and fled into streets across West Bengal, including in Kolkata [47] and Bidhannagar. [48] A Modified Mercalli intensity (MMI) of III (Weak) was estimated in Basirhat and Balurghat. [4] Tremors were also felt in Berhampore, Krishnanagar, Kalyani and Howrah. [49]
In Bangladesh, the Dhaka District Administration established an emergency control room to conduct support and relief to affected areas. [50] The government also established a control room for help in damage assessments. [51] Financial assistance was offered to the victims by the central government, which offered 25,000 taka for families of the deceased and 15,000 taka for those injured. [52] The Dhaka District Administration offered 15,000 taka to each injured person to help shoulder their treatment. [53]
Embassies of the United States and France, and supranational organizations including the United Nations, the European Union and the BIMSTEC expressed sympathies to victims of the earthquake and their families. [54]
Many experts warned that the earthquake may be a prelude of a more powerful and deadlier earthquake in the region, as it sits on the collision zone of two tectonic plates. [55] [56] Earthquake expert Humayun Akhtar calculated that less than 1% of the energy stored in the subduction zone was released from the earthquake and its aftershocks, and there is high possibility of a major quake of a magnitude of 8.2–9 in the region in the near geological future. [57]
Experts estimated that an earthquake of magnitude 6 to 6.5 on the Madhupur fault can risk nearly 10 million people's life across the districts of Dhaka, Gazipur, Mymensingh and Tangail; and the fault is capable to generate earthquakes of magnitude 7 to 7.5 at any time. [58] Following the earthquake, RAJUK said it had identified nearly 300 buildings that were at risk in Dhaka. [59] It also estimated that an earthquake of a magnitude of 6.9 in the fault may result in 210,000 fatalities, 229,000 injuries and the collapse of 865,000 buildings in Dhaka. [60]
Prothom Alo Fact-checking found that social media users falsely linked media of the 2015 Nepal and 2025 Myanmar earthquakes, as well as AI-generated content to the earthquake in Bangladesh. Some of them were also used by Indian and Pakistani media and news portals, including Republic Bangla . Pro-Awami League accounts spread rumours of the tilting of the Chief Adviser's Office. [61] An "earthquake-infodemic" was also created through rumours and "warnings" of an upcoming major earthquake spread through WhatsApp and Facebook. [62]
