No tsunami threat after PNG quake

A strong 6.5-magnitude earthquake struck beneath the sea off Papua New Guinea  this morning, US seismologists said, but there was no threat of a subsequent  tsunami.

There were no immediate reports of casualties or damage from the quake, which  hit at 4.37am AEST at a depth of 43 kilometres, about 120 kilometres west of the  island of Bougainville in Papua New Guinea.

“Earthquakes of this size sometimes generate local tsunamis that can be  destructive along coasts located within 100km of the earthquake epicentre,” the  tsunami warning centre said in a statement.

The Joint Australian Tsunami Warning Centre said there was no threat to  Australia.

Papua New Guinea sits on the Pacific “ring of fire”, a hot spot for seismic  activity due to friction between tectonic plates.

A giant tsunami in 1997, caused by an undersea earthquake or landslide,  killed more than 3500 people near Aitapi, on the northwest coast of mainland  Papua New Guinea.

In 2007 a tsunami after an 8.1-magnitude earthquake killed at least 52 people  in the Solomon Islands and left thousands homeless.
