An earthquake with a magnitude of 6.5 on the Richter scale hit Indonesia's Sumatra Island Sunday, but no injuries or tsunami warnings were reported initially.

An India-based meteorology agency measured the quake at 6.5, while the U.S. Geological Survey had it at 6.4. The temblor was felt throughout the island's Bengkulu province and in the province of West Sumatra, the state-run Chinese news agency Xinhua reported.

The U.S. group told CNN the quake was followed by an aftershock measuring 5.5 an estimated 11 minutes after the primary quake occurred.

The USGS said the quake originated nearly 95 miles away from the West Sumatra capital of Padang.

The Bengkulu province of Sumatra Island suffered another major quake in 2007 when a 7.9 magnitude quake devastated the Indonesian region, Xinhua reported. That quake leveled thousands of buildings in the area and left 23 people dead.

Indonesia is particularly prone to quakes due to the country's presence in the so-called "Pacific Ring of Fire," a region where two continental plates meet and are the site of significant volcanic movements.
