JAKARTA - A 6.5-magnitude earthquake jolted off the south coast of Indonesia's scenic island of Bali early Tuesday, the Indonesian Meteorological, Climatological and Geophysical Agency reported, but no casualties or damage have been reported so far.

The quake struck at 18:23 GMT (01:23 Jakarta time) on Monday. The epicenter was 301 km south of Banyuwangi Regency, East Java province, 290 km from Bali's capital Denpasar with a depth of 10 km under the sea.

The United States Geological Survey (USGS) put the magnitude at 6.4 with a depth of 8.8 km. The Indonesian Meteorological and Geophysics Agency said there was no potential to generate a tsunami.

Indonesia sits on the so-called Pacific "Ring of Fire" where several tectonic plates meet, making it vulnerable to frequent earthquakes.
