A magnitude-6.8 earthquake struck underwater near Nias island in Indonesia late Tuesday, with no immediate reports of injuries or damage, seismologists reported.

The US Geological Survey placed the quake at 10:28 pm local time, about 270 kilometers southwest of Sibolga, Sumatra, at a shallow depth of roughly 1.9 kilometers. The Pacific Tsunami Warning Centre said the event posed no broad tsunami danger, though it noted a slight chance of a localized tsunami within about 100 kilometers of the epicenter.

Nias suffered severe devastation in the 26 December 2004 disaster, when a 9.3-magnitude quake triggered a tsunami that killed more than 220,000 people across the Indian Ocean region, including roughly 168,000 in the Indonesian province of Aceh.

Indonesia lies along the Pacific Ring of Fire, a zone of intense seismic activity created by colliding tectonic plates. A major fault line running parallel to Sumatra has repeatedly produced powerful earthquakes in the region.
