4.1 Magnitude Earthquake Strikes Bangladesh at 150km Depth

An earthquake measuring 4.1 on the Richter scale struck Bangladesh, occurring at a significant depth of 150 kilometers. The country is situated at a seismically active convergence of the Indian, Eurasian, and Burma tectonic plates. With five major fault zones, Bangladesh contains 13 areas prone to earthquakes, with some regions at extreme risk. The high population density of cities like Dhaka exacerbates the potential human impact, placing it among the world's 20 cities most vulnerable to earthquakes.

Key Points: 4.1 Magnitude Earthquake Hits Bangladesh

  • Magnitude 4.1 quake at 150km depth
  • Occurs at Indian-Eurasia-Burma plate junction
  • Bangladesh has 13 earthquake-prone areas
  • Dhaka among world's 20 most vulnerable cities

Earthquake of magnitude 4.1 strikes Bangladesh

A 4.1 magnitude earthquake struck Bangladesh at a depth of 150km. Learn about the country's seismic risk zones and tectonic plate movements.

"EQ of M: 4.1, On: 03/02/2026 04:06:46 IST, Lat: 22.84 N, Long: 89.01 E, Depth: 150 Km, Location: Bangladesh. - National Centre for Seismology"

Dhaka, February 3

An earthquake of magnitude 4.1 struck Bangladesh on Tuesday, a statement by the National Centre for Seismology said.

As per the NCS, the earthquake occurred at a depth of 150km.

In a post on X, the NCS said, "EQ of M: 4.1, On: 03/02/2026 04:06:46 IST, Lat: 22.84 N, Long: 89.01 E, Depth: 150 Km, Location: Bangladesh."

It is estimated that an earthquake occurs every 30 seconds somewhere on Earth. But the bulk of those are too weak to be identified. A magnitude of 4.0 earthquake is only equivalent to about 6 tons of TNT explosives, but because the Richter scale is a base-10 logarithmic scale, the amount of energy released increases exponentially: A magnitude 5.0 earthquake is about 200 tons of TNT, 7.0 is 199,000 tons, and 9.0 is 99,000,000 tons of TNT, The Daily Star reported.

About 99 million tons of TNT is enough to wipe out just about anything, and is the equivalent of about 25,000 nuclear bombs, according to USGS.

Bangladesh sits where the three tectonic plates - Indian-Eurasia-Burma - meet. Currently, the Indian plate is moving in the north-east at a speed of approximately 6cm per year and the Eurasian plate is moving north at a speed of 2cm per year above the Indian plate. There are five major fault zones in and around Bangladesh, namely Bogura fault zone, Tripura fault zone, Shilong Plateau, Dauki fault zone and Assam fault zone, The Daily Star reported.

Thus, Bangladesh is a location of 13 earthquake prone areas, and Chattogram, Chattogram Hill Tracts, and Jaintiapur of Sylhet remain in extreme risk zones. In 2022, Dhaka, the capital of Bangladesh, with 30,093 residents per square kilometer was among cities with the highest population density in the world. And has been marked as one of the 20 cities most vulnerable to earthquakes in the world, as per The Daily Star.

The tectonic plate explanation is fascinating. The Indian plate moving 6cm/year... it's a constant, slow-motion collision. Makes you realize how dynamic and fragile the ground beneath us really is.

We share the same seismic risks in Northeast India. Assam, Silchar, Guwahati are also in high-risk zones. Maybe India and Bangladesh should collaborate more on earthquake preparedness and early warning systems. It's a common threat.

The comparison to TNT and nuclear bombs is terrifying! 9.0 = 25,000 nukes? 😳 Puts the sheer power of nature into perspective. Hope the authorities in vulnerable areas are taking building codes seriously.

While the article is informative, it jumps from a specific 4.1 event to apocalyptic 9.0 scenarios. A bit of fear-mongering? The focus should be on practical preparedness for the more likely medium-intensity quakes.

Glad no casualties reported. These frequent small tremors are nature's reminders. In India too, we need better public awareness drills. Does your housing society even know what to do during an earthquake? Most don't.
