A strong earthquake struck deep under the sea in eastern Indonesia on Saturday, but there were no immediate reports of damage or injuries, officials said.
The earthquake of a preliminary magnitude of 6.0 struck on the fifth anniversary of another quake that spawned the Asian tsunami that left 230,000 people dead in a dozen countries around the Indian Ocean rim. The December 26, 2004 tsunami was sparked by a 9.2-magnitude underwater quake off the Indonesian island of Sumatra.
Saturday's quake was at a depth of 57 kilometers, too far below the earth's surface to cause a tsunami, said Indonesian Meteorology and Geophysics Agency seismologist Paulus Prihandoyo.
The quake had its epicenter about 270 kilometers north of Saumlaki and about 2,700 kilometers east of the capital Jakarta, the US Geological Survey said.
