Tsunami warning for PNG after magnitude 7.5 quake

TSUNAMI waves up to a metre above sea level could be heading for the coast of Papua New Guinea coast following a magnitude 7.5 earthquake that struck off the nation's coast.

The Pacific Tsunami Warning Center put out the alert after the quake struck 130km south of Kokopo in the New Britain region of PNG at 11am AEST.

The PTWC has warned tsunami waves could reach between 30cm and 1m above sea level for coastal parts of PNG.

It warned that if the waves were to strike, they would reach the PNG coastline just before 1pm AEST or 2.55am GMT.

There is not expected to be any threat to Australia, according to the Bureau of Meteorology.


According to Joint Australian Tsunami Warning Centre co-director Daniel Jaksa, any potential tsunami would be "small".

The coastlines most likely to be affected were also quite isolated.

"This region of Papua New Guinea is very, very sparse in population," he said.

"We wouldn't expect anything to happen there."
