A 5.4 magnitude earthquake struck the Andaman Sea region on Monday morning, according to the National Centre for Seismology (NCS). The tremors were felt across parts of the Andaman and Nicobar Islands, though officials confirmed there were no immediate reports of casualties or damage to property.
The quake was recorded at around 8:45 AM IST, with its epicentre located in the Andaman Sea, approximately 110 km east of Port Blair, at a depth of nearly 35 kilometres.
No Tsunami Threat, Says Authorities
Officials from the Indian Tsunami Early Warning Centre (ITEWC) ruled out any threat of a tsunami following the tremor. “Our assessment shows no significant sea-level changes. There is no danger of a tsunami for the Indian coastline,” an ITEWC spokesperson said.
Residents of Port Blair, Rangat, and Havelock reported mild shaking lasting a few seconds, prompting some people to rush outdoors. However, normal activities resumed shortly after.
“The tremors were noticeable but brief. We stepped out of our homes for safety, but there was no panic,” said a local resident from Port Blair.
Seismological Details
According to the National Centre for Seismology, the quake’s coordinates were 10.50°N latitude and 93.00°E longitude, placing it in the seismically active Andaman Subduction Zone — an area known for frequent moderate-intensity earthquakes.
The Andaman and Nicobar region lies near the boundary of the Indian and Burmese tectonic plates, making it prone to undersea quakes. However, most tremors here are of moderate magnitude and rarely cause significant damage.
Historical Context
The region has witnessed several notable quakes in the past. The 2004 Indian Ocean earthquake and tsunami, which originated near the Sumatra-Andaman trench, remains the most devastating event in the area’s history. Since then, continuous seismic monitoring and tsunami preparedness systems have been put in place.
Officials said Monday’s quake was a routine tectonic event and not related to any major fault movement. Still, local authorities remain on alert, and NCS scientists are monitoring aftershock patterns.
Safety Measures Advised
Experts reminded residents to follow basic earthquake safety protocols in the event of future tremors:
Move to an open area away from buildings and power lines.
Stay indoors if already in a stable structure — take cover under sturdy furniture.
Keep an emergency kit and torch handy.
Follow updates from official government agencies only.
No aftershocks were recorded as of Monday afternoon.
