NCS took to X and informed about the seismic activity. “EQ of M: 4.1, On: 25/01/2026 02:42:49 IST, Lat: 37.09 N, Long: 71.16 E, Depth: 112 Km, Location: Afghanistan,” NCS wrote.

Why Shallow Earthquakes Pose Greater Risk

According to experts who monitor seismic activity, shallow quakes are more dangerous, as they cause greater damage than deeper ones.
Shallow quake waves travel a shorter distance and reach the surface faster.
This leads to stronger ground shaking and higher destruction.
