A magnitude 5.1 earthquake struck the Andaman Sea on Thursday, October 29, 2026, with tremors reported in parts of the Andaman and Nicobar Islands. The National Centre for Seismology (NCS) recorded the event, with the epicentre reported around 218 kilometres north-northwest of Bamboo Flat. The tremors were felt at approximately 3:19 PM, according to reports quoting local officials.
Where did the earthquake occur?
The earthquake was located in the Andaman Sea, off the island chain. Reports citing the NCS placed the epicentre around 218 kilometres north-northwest of Bamboo Flat, in the Andaman and Nicobar Islands. The event was reported at a shallow depth of around 10 kilometres. Earthquakes at relatively shallow depths can be felt over a wider area, depending on the magnitude, local geology and distance from the epicentre.
Tremors reported in North and Middle Andaman
Officials received reports of mild tremors from some parts of North and Middle Andaman. The shaking was reported by residents, while authorities said there were no immediate reports of loss of life or damage to property. The District Emergency Operation Centre in Sri Vijaya Puram said agencies had been alerted and standard response protocols were in place.
Precautionary advisory for tourists and fishermen
As a precaution, tourists and fishermen were advised not to venture into the sea until authorities had assessed the situation. Such advisories are intended to reduce risk while officials monitor seismic activity and check for any related sea-level changes. Residents and visitors should follow directions issued by local administration, disaster management teams and maritime authorities rather than relying on unverified social media messages.
Was a tsunami warning issued?
The available reports cited here did not indicate an immediate tsunami warning or confirmed damage. An earthquake does not automatically lead to a tsunami; the risk depends on several factors, including the location, depth, magnitude and nature of seabed movement. People in coastal areas should continue to follow official alerts from the relevant authorities and avoid sharing speculative warnings.
What residents should do
Residents should stay away from damaged structures, secure heavy objects where possible and keep emergency contact information accessible. If another tremor occurs, follow standard earthquake safety guidance: drop, cover and hold on indoors, and move away from windows and unstable objects. Visitors should pay attention to local instructions and avoid beaches or boat trips if authorities advise against them.
Officials continue to monitor the situation. The key information available so far is that a 5.1-magnitude earthquake occurred in the Andaman Sea, mild tremors were reported in parts of the islands and no immediate casualties or property damage had been reported.
