A tsunami warning has been issued for coastlines near the epicentre of a magnitude 7.4 earthquake that struck off Papua New Guinea.
The US Geological Survey issued an alert saying the quake struck 13km south of Kokopo, in the New Britain region of the island nation, at a depth of 50km.
The Pacific Tsunami Warning Centre said hazardous tsunami waves reaching 0.3 to 1m were possible for Papua New Guinea coastlines located within 300km of the earthquake epicentre.
Preliminary reports said the quake was a magnitude 7.5 at a depth of 10km, but that information has since been updated.
According to data from the USGS, there have been several recent earthquakes in the area.
A 7.5 magnitude earthquake was recorded on the 29th of March, 53km to the south-east of Kokopo.
A 6.7 magnitude earthquake struck to the south-west of Kokopo on the 30th of April this year, quickly followed by a 6.8 magnitude earthquake the following day.
