Papua New Guinea authorities are assessing the extent of damage from a powerful earthquake that rattled coastal towns yesterday evening.

The magnitude 7.5 quake struck around 11 pm Tuesday (local time) at a relatively shallow depth of 10km, according to the US Geological Survey. It was offshore about 45km northeast of Kokopo, which has about 26,000 people.

Journalist Andrew Beatty this morning said aftershocks were still being felt.

"The manager of a local hotel told AFP the earthquake in Papua New Guinea was "massive, absolutely massive. Very scary"," he said.


Chris McKee, the acting director of geohazards management, said there was some damage in Kokopo as items were shaken from shelves and the power had been cut. He said a small tsunami was generated, but the late-night darkness made an assessment difficult.

McKee said the earthquake was a strike-slip event along a fault line, a type of quake that doesn't usually trigger major tsunamis.

Garfield Tarabu, a spokesman at the National Disaster Centre, said a disaster coordinator was on the ground assessing the situation in and around Kokopo but they hadn't yet gotten an update on the extent of the damage.

The US Pacific Tsunami Warning Center had said tsunami waves of up to 1m were possible along coastal areas up to 1,000km from the epicentre, including Papua New Guinea and the nearby Solomon Islands.

The warning has now been lifted.

Papua New Guinea is located on the eastern half of the island of New Guinea, to the east of Indonesia and north of eastern Australia.

It sits on the Pacific's "Ring of Fire," the arc of seismic faults around the Pacific Ocean where much of the world's earthquakes and volcanic activity occurs.

A magnitude 7.5 earthquake in 2018 in the nation's central region killed at least 125 people. That quake hit areas that are remote and undeveloped, and assessments about the scale of the damage and injuries were slow to filter out.
