A shallow 6.1-magnitude earthquake struck off the coast of Fiji on Saturday, the US Geological Survey said, but there were no immediate reports of damage.
The quake, recorded at 6:11 pm (0611 GMT) was centred 152 kilometres southwest of Nadi and 238 kilometres from thecapital Suva at a depth of 10 kilometres.
A 7.2-magnitude earthquake was recorded in the same region a week ago. That tremor was felt in Nadi but did not cause any damage. The area lies on the Pacific "Ring of Fire", a highly active tectonic zone that frequently experiences earthquakes and volcanic eruptions.
