WASHINGTON (REUTERS) - A magnitude 7.8 earthquake hit 105km east-southeast of Suva, Fiji, at a depth of 608km, the US Geological Survey said on Thursday (Sept 6).

The measure was revised downward from an initial magnitude 8.1 reading by USGS.

The Pacific Tsunami Warning Centre said no destructive Pacific-wide tsunami was expected, and there was no tsunami threat to Hawaii.

New Zealand's Ministry of Civil Defence and Emergency Management said there was no tsunami threat to New Zealand following the earthquake.
