An earthquake today: According to the statement of India, the National Center for Seismology (NCS) shared in a post on social media on the X platform.
The NCS shared data stressed that in the Bangladesh’s earthquake occurred at 11:49 (ist) at a shallow depth of 10 kilometers, which is susceptible to shocks.
“EQ M: 4.0, on: 21/09/2025 11:49:36 AM, LAT: 25.04 N, Long: 91.57 E, depth: 10 km, location: Bangladesh,” said the National Center for Seismology.
What are shallow earthquakes?
Shallow earthquake is generally more dangerous than deep earthquakes. This natural phenomenon occurs because seismic waves from shallow earthquakes travel to a shorter distance to the surface, resulting in stronger fraying of the Earth, potentially greater damage to structures and greater victims.
According to the Daily Star report, it is estimated that an earthquake occurs every 30 seconds somewhere around the world; However, most of them are too weak to identify.
The 4.0 magnitude earthquake corresponds to about 6 tonnes of TNT explosives, but since the Richter scale is a logarithmic scale Base-10, the amount of energy released increases exponentially: the size of 5.0 earthquakes is about 200 ton TNT, 7.0 is 199,000 tons and 9.0 is 99,000,000 tonnes.
The message, which quoted USGS data, said that nearly 99 million tons of TNT sufficiently sufficient to smooth almost anything, and is equivalent to about 25,000 nuclear bombs.
Bangladesh sits, where three tectonic plates – Indian, Eurasian and Burma – meet. Currently, the Indian plate is in the northeast at a speed of approximately 6 cm per year, and the Eurasian plate is north at a speed of 2 cm per year above the Indian plate.
Bangladesh is reported to have five major fault zones: Bogura, Tripura Fault Zone, Shilong plateau, Dauki and Assam Fault Zone.
Thus, Bangladesh has 13 areas susceptible to earthquakes and chattogram, hills of the cottage and jaintiapur from Sylhet remain in extreme risky zones. In 2022, Dhaka, the capital of Bangladesh with 30,093 inhabitants per square kilometer, with the highest population density in the world. It was also described as one of the 20 cities most vulnerable to the earthquake in the world.
