TOLOTANGGA, Indonesia -- A magnitude-6.2 earthquake hit a region in the eastern part of Indonesia this morning, the U.S. Geological Survey reported.

The earthquake hit about 6:30 a.m. local time in the Sumbawa region, the agency said. The epicenter was about 20 miles south of the village of Tolotangga, which is 840 miles east of the nation's capital, Jakarta.

The earthquake was about 45 miles deep, the agency said.

In a statement, Indonesia's National Disaster Mitigation Agency said the earthquake also was felt in the neighboring province of East Nusa Tenggara and the tourist island of Bali.

The earthquake caused many residents in the areas hit to pour out from their houses, the agency said. But it added there were no immediate reports of damages or casualties.

No tsunami warning has been issued, according to the U.S. Geological Survey.

On Dec. 7, Indonesia's Aceh province was hit by a magnitude-6.5 quake that killed more than 100 people.

The world's largest archipelago, Indonesia is prone to earthquakes due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

A 2004 quake and tsunami killed 230,000 people in a dozen countries, most of them in Aceh.
