An earthquake measuring magnitude 5.8 has struck between Samoa and the islands of northern Tonga.
The US Geological Survey reports the epicentre of the quake was just shy of 200 kilometres southwest of the Samoan capital Apia and about 100 kilometres from Hihifo in Tonga.
It was nearly 30 kilometres deep and struck about an hour and a half ago (05.36 UTC, 18.36 NZT).
The Samoan Police Commissioner Egon Keil says Apia certainly shook but he's received no reports of damage or injury.
Other residents in Apia say the quake shook items off shelves.
