Strong earthquake rattles Indonesia

• Indonesia is prone to frequent earthquakes and volcanic eruptions
• There are no immediate reports of injuries or damage

(CNN) -- A strong earthquake hit off the coast of Sumatra in Indonesia on Friday, the U.S. Geological Survey reported.

The 6.2-magnitude shook the Kepulauan Mentawai region

Its epicenter was 760 kilometers (470 miles) west-northwest of the capital, Jakarta, at a depth of 20 kilometers, according to the USGS.

There were no immediate reports of injuries or damage.

Last month, a 6.6-magnitude earthquake hit Palu city on the island of Sulawesi, killing at least six people.

Indonesia is on the so-called Ring of Fire, an arc of fault lines circling the Pacific Basin that is prone to frequent earthquakes and volcanic eruptions.
