A powerful earthquake struck waters off western Indonesia on Saturday, but local officials said there was no risk of a tsunami.
The U.S. Geological Survey said the quake had a preliminary magnitude of 6.8 and hit 100 miles southwest of Bengkulu, a city on Sumatra island. It was centered 16 miles beneath the ocean floor.
Fauzi, an official with Indonesia's geological agency, said the temblor did not trigger a tsunami and there were no immediate reports of damage. Like many Indonesians, he only has one name.
Indonesia is prone to seismic upheaval due to its location on the so-called Pacific "Ring of Fire," an arc of volcanoes and fault lines encircling the Pacific Basin.
In December 2004, a massive earthquake off Sumatra island triggered a tsunami that battered much of the Indian Ocean coastline and killed more than 230,000 people.
