The acting director of the Papua New Guinea National Disaster Office, Martin Mose, says they have not received any reports of damage following a tsunami alert.
The Pacific Tsunami Center issued a warning for a tsunami after a quake near New Ireland in PNG this morning.
The tremor measured 7.6 and was at a depth of 33 kilometres.
The Center said waves of up to 3 metres were possible in PNG and up to 0.3 metres for much of the rest of the Pacific.
But it withdrew the warning several hours later.
Mr Mose says a small wave, estimated at about half a metre, did occur at Rabaul -- one of the closest towns to the epicentre.
But he says he is not expecting reports of any damage or injury.
"Up to now we have not received any reports of any damage caused by the tsunami. Now, because of the isolation reports may be slow to get to the provincial headquarters to reach the national office, but i would assume that if there was any impact then it would have been minimal"
