Earthquakes over six in magnitude have struck near Fiji and Indonesia early today.
The first - 6.4-magnitude - struck the Fiji region around 2.05am, according to the US Geological Survey.
The undersea quake hit 32km west of Suva at a depth of 555km.
This morning's second six-plus magnitude shake measured 6.7 and was centred south of Java, Indonesia, at 8.06 o'clock. No depth has yet been given.
The Pacific Tsunami Warning Centre issued a "localised" tsunami warning for Indonesia, but there was no such warning for areas around the Fiji quake.
"There is a very small possibility of a local tsunami that could affect coasts located usually no more than a 100 kilometres from the earthquake epicentre," the PTWC said regarding the Indonesian quake.
