The quake at a depth of 33 km under the sea off northern Aceh province occurred at 2:38 pm local time, U.S. Geological Survey said.
The quake triggered a tsunami warning across the Indian Ocean region.
Pacific Tsunami Warning Center said quakes of such a magnitude "have the potential to generate a widespread destructive tsunami that can affect coastlines across the entire Indian Ocean basin".
