A MASSIVE magnitude 8.2 earthquake rocked the South Pacific and sparked tsunami waves early on Sunday.

The powerful tremor struck off Ndoi Island, Fiji, and was initially recorded as a 7.9 magnitude quake before being revised, according to the US Geological Survey.

The Pacific Tsunami Warning Center tweeted: "Fiji #earthquake magnitude revised to 8.2 and small, non-dangerous #tsunami waves have been observed.

"While no hazard is expected for any coastline, but please be observant and exercise normal caution."

The quake struck at 560km deep, so it was initially deemed unlikely to spark a "destructive Pacific-wide" tsunami, but small waves were later observed.

GeoNet, which monitors earthquakes, volcanoes, tsunamis and landslides in New Zealand said the tremor generated "ghost quakes" in its systems.

It said on Twitter: "Some 'ghost quakes' (not real) have been [generated] by our auto-location system 30mins ago.

"The real quake was VERY deep (560km) magnitude 8.2, 281 km from Fiji, The location & depth means it won't have caused damage, these deep quakes don't cause tsunami."

So far, there is no information on damages, or injuries.
