Indonesia’s Geophysical Agency has registered a 6.5 aftershock following an earlier 8.6 magnitude quake in Aceh region off the coast of northern Sumatra. A tsunami warning has been issued across the Indian Ocean, the US Geological Survey reports.


Indonesia’s Geophysical Agency says a fresh aftershock of 8.2 magnitude has hit off the Sumatra province of Aceh. A new fresh tsunami warning has been issued.


Indonesia’s disaster mitigation agency is sending a rescue team to Aceh, after the quake knocked out the province’s electricity and sent locals scrambling for higher ground, Reuters says.

Waves from a possible tsunami could reach the provincial capital Banda Aceh shortly, according to the Pacific Tsunami Warning Center.

“Earthquakes of this size have the potential to generate a widespread destructive tsunami that can affect coastlines across the entire Indian Ocean basin,” a warning from the PTWC reads. “Authorities in the region should take appropriate action in response to the possibility.”


Indonesia’s president stated that the country as yet faced “no tsunami threat, but we are on alert”. At this time, Indonesia’s Geophysical Agency has not received reports of damage or rise in water levels in Aceh – communication with the region is poor.

Banda Aceh is the closest city to the quake’s epicenter, which lies 33 km beneath the ocean floor. The city has a population of over 220,000, and is situated some 500 kilometers away from the epicenter. Its port remains open, a local official said. Aceh province was the main victim of the massive 2004 quake and tsunami in the Indian ocean.

Tremors from the quake have been felt in Singapore, Thailand, Malaysia and southern India. Witnesses said on Twitter that high-rise buildings and offices on Malaysia’s west coast shook for at least a minute. India’s port of Chennai shut after the quake, a local official told Reuters.

Indonesia straddles a series of fault lines that makes the vast island nation prone to volcanic and seismic activity.

In December 2004, a giant 9.1 quake triggered a tsunami in the Indian Ocean that killed 230,000 people, nearly three quarters of them in Aceh.
