Kathmandu: The National Centre for Seismology (NCS) said that a magnitude 4.0 earthquake rocked Nepal on Tuesday. According to the NCS, the 25-kilometre depth at which the earthquake occurred made it vulnerable to aftershocks.
The NCS said in a statement on X that “EQ of M: 4.0, On: 15/04/2025 04:39:02 IST, Lat: 28.76 N, Long: 82.01 E, Depth: 25 Km, Location: Nepal.”
In contrast to deeper earthquakes, which lose energy as they approach the surface, shallow earthquakes are more destructive because they release more energy closer to the ground, resulting in harsher ground shaking, more damage to buildings, and more fatalities. The eleventh most earthquake-prone nation in the world is Nepal.
Nepal is located near the Himalayas, an area known for its high earthquake activity. It is situated where the Indian and Eurasian tectonic plates meet at a convergent border. The crust experiences stress and strain as a result of this contact, which is ultimately released as earthquakes.
The Indian Plate is slipping under the Eurasian Plate in the subduction zone where Nepal is situated. Earthquakes in Nepal may result from this subduction process, which also puts additional stress and pressure on the crust. The Himalayan mountains were raised as a result of these plates colliding. Earthquakes may result from the tremendous strain and tension created by this movement.
Unreinforced masonry, which is not particularly strong and readily collapses in an earthquake, is used to construct a large number of structures in Nepal. After an earthquake, it may be challenging to provide aid and relief since a large portion of Nepal is isolated and hilly.
