A magnitude 6.0 earthquake struck off the coast of Indonesia's Sumatra island early Tuesday morning, according to the U.S. Geological Survey.
No tsunami alert was immediately issued and there were no reports of damage or casualties.
The quake, which hit at 3:12 a.m. local time (2012 GMT), was centered about 110 miles (175 kilometers) southwest of Tanjungkarang-Telukbetung on the island of Sumatra, according to the U.S.G.S. Its recorded depth was 19 miles (31 kilometers).
Indonesia's meteorology and geophysics agency recorded it as a shallow 6.2-magnitude quake.
The quake, which struck about 195 miles (315 kilometers) west of Jakarta, was felt in the coastal town of Krui in Lampung province and Kepahyang in nearby Bengkulu province, said Dedi Sugianto of Indonesia's meteorology agency, who added there were no signs of damage.
Indonesia straddles a series of fault lines that make the vast island nation prone to volcanic and seismic activity.
