A strong earthquake shook buildings and sent people scrambling from their homes early Monday in Banda Aceh (search), but no injuries or damage were reported in the Indonesian city that was devastated by a massive quake and tsunami (search) two weeks ago.

The magnitude 6.2 temblor struck at 5:13 a.m. off the northern coast of Sumatra island (search), according to the U.S. Geological Survey's Web site.

The quake was centered at a depth of about nine miles under the seabed in the Indian Ocean, about 40 miles southwest of Banda Aceh, the USGS said.

Sumatra, which was closest to the epicenter of the Dec. 26 magnitude 9.0 earthquake that triggered the killer tsunami, has accounted for about two-thirds of the 150,000 people known to have died in the disaster, which ravaged 11 countries in Asia and Africa.

In Banda Aceh alone, 40,000 people were killed and many more were left homeless and traumatized after giant waves tore through the city.
