Seismic activity reported in neighboring nations early Tuesday morning
Two separate seismic events were recorded in neighboring regions on Tuesday, February 3, 2026. The National Centre for Seismology (NCS) confirmed that a magnitude 4.1 earthquake struck Bangladesh, while a separate, shallower tremor was recorded in Tibet.
Bangladesh Tremors and Seismic Risks
According to official data from the NCS, the earthquake in Bangladesh occurred early in the morning at 04:06 IST. The epicenter was located at latitude 22.84 N and longitude 89.01 E, with a significant depth of 150 km. While a magnitude 4.1 quake is generally considered moderate—releasing energy equivalent to approximately 6 tons of TNT—the region remains a concern for seismologists.
Bangladesh is geographically positioned at a complex junction where the Indian, Eurasian, and Burma tectonic plates meet. Experts note that the Indian plate is currently moving northeast at roughly 6 cm per year. This constant geological pressure makes areas like Chattogram and Sylhet high-risk zones. Additionally, Dhaka faces significant vulnerability due to its extremely high population density, which complicates disaster management in urban centers.
Shallow Quake Hits Tibet
Later in the morning, at 10:17 IST, the NCS reported a second event in Tibet. This earthquake measured 3.2 on the Richter scale but occurred at a much shallower depth of just 10 km.
Seismologists warn that shallow earthquakes, despite having lower magnitudes, can sometimes be more dangerous than deeper ones. Because the seismic waves originate closer to the surface, they travel a shorter distance, often resulting in more intense ground shaking. Tibet’s seismic activity is largely driven by the ongoing collision between the Indian and Eurasian plates, a geological process responsible for the formation and continued elevation of the Himalayas.
While no immediate damage was reported from either event, these occurrences serve as a reminder of the volatile seismic nature of the Indian subcontinent and its surrounding regions.
