JAKARTA: A magnitude 6.5 earthquake rocked India's Nicobar Islands region early Tuesday but did not trigger a tsunami alert, the United States Geological Survey and Tsunami Warning System said.
The quake struck at a depth of 10 kilometres (six miles) at 12 minutes past midnight local time (18:42 GMT Monday), 259 kilometers west-northwest of Sabang, in western Indonesia's Aceh province, the USGS said.
Aceh was the area most devastated by the magnitude-9.1 earthquake and tsunami that killed more than 220,000 people in 15 countries in 2004.
Further details are awaited.
