JAKARTA, Indonesia A powerful earthquake has struck the province in Indonesia that was hardest hit by the 2004 tsunami.

The magnitude six-point-three quake sent residents running from buildings today in Aceh (AH'-cheh), but there are no reports on injuries or damage. Officials say the quake also triggered panic on nearby islands.

The U-S Geological Survey says the quake was centered 18 miles beneath the Indian Ocean and 50 miles southwest of Aceh's capital.

In December 2004, a massive earthquake struck off Indonesia's Sumatra island and triggered a tsunami that killed more than 230-thousand people, including 160-thousand people in Aceh.

A tsunami off Java island last year killed nearly five-thousand.
