A TSUNAMI warning has been issued for Papua New Guinea, following a 7.6-magnitude earthquake.

The earthquake has rocked the region of New Ireland at a depth of about 33 kilometres.

The Pacific Tsunami Warning Centre is warning that huge waves are possible up to 1,000 kilometres.

“Based on the preliminary earthquake parameters, hazardous tsunami waves are possible for coasts located within 1,000 kilometres of the earthquake epicentre”, the Warning Centre says.

In its latest update, the PTWC said waves between 1 and 3 metre waves are possible in PNG.

Tsunami waves are predicted to be above 0.3 metres at Woodlark Island and Kavieng, PNG.

As a tsunami is comprised of a series of waves, the time between waves can vary from 5 minutes to an hour.

Impacts of the waves will also vary, and the first wave will not necessarily be the biggest one, PTWC warned.
