5.3 Magnitude Earthquake Hits Indian Ocean: Third Seismic Event in One Day Raises Concerns
Nov 28, 2025 12:05 am CST
A magnitude 5.3 earthquake struck the Indian Ocean on Thursday at a shallow depth of 10km, as reported by the National Centre for Seismology. This marks the third seismic event in the region within 24 hours, following earlier tremors of magnitudes 6.4 and 4.8. The shallow nature of these earthquakes raises concerns due to their greater potential for surface damage compared to deeper seismic activities. The region has a history of devastating earthquakes, most notably the 2004 Sumatra-Andaman event that triggered the deadliest tsunami in recorded history.

A 5.2 magnitude earthquake hit Pakistan on November 21, 2025, with its epicentre at a depth of 135 km. This seismic event highlights Pakistan's position in one of the world's most active earthquake zones, where the Indian and Eurasian tectonic plates meet. The country's geological positioning makes regions like Balochistan, Khyber Pakhtunkhwa, and Punjab particularly vulnerable to frequent earthquake activity along major fault lines.
