A tsunami warning has been issued after an earthquake near New Ireland in Papua New Guinea.
The Pacific Tsunami Warning Centre in Hawaii says waves of up to three metres are possible in parts of Papua New Guinea.
The 7.6 magnitude quake struck late this morning (PNG time) at a depth of about 33 kilometres. The epicentre of the quake was near the town of Rabaul.
The centre says waves of less than 0.3m could also occur across much of the western Pacific.
It says the waves could vary from the forecast, due to uncertainties in the forecast and local features.
It says wave height on atolls is likely to be much smaller that the forecast indicates.
Residents in East New Britain contacted by Radio New Zealand International reported a strong tremor but no damage.
