Magnitude-6.6 underwater hits off east Indonesia, no tsunami threat

A magnitude-6.6 earthquake has rocked Indonesia's easternmost province, but there were no immediate reports of casualties or damage.

The quake, struck at 00:53 a.m. Saturday (1553 GMT Friday), was centered about 28 kilometers (17 miles) north of Sorong, a town of Indonesia's West Papua province, the U.S. Geological Survey said on its Web site. It occurred at a depth of 24 kilometers (15 miles).

Hundreds of people fled their homes in panic in Sorong and Manokwari city, 315 kilometer (195 miles) to the west, according to residents contacted by telephones, but no tsunami warnings have been posted.

Many parts of Indonesia, the world's largest archipelago, are prone to seismic upheavals because of their location on the "Ring of Fire," the chain of volcanoes and earthquake zones circling the Pacific Ocean.
