A local tsunami alert was raised by the Pacific Tsunami Warning Center after a strong earthquake has been recorded at 6.5 magnitude.

According to US seismologists, the tremor had hit beneath the sea off Papua New Guinea on Monday.

No immediate reports of casualties or damages caused by the shaking were received by the local authorities. The catastrophe transpired around 4:37 a.m. AEST at depth of 43 kilometers, around 120 kilometers west of the island of Bougainville in Papua New Guinea.

In an interview, the tsunami warning center stated, "Earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within 100km of the earthquake epicenter," the tsunami warning center said in a statement.

The Joint Australian Tsunami Warning Centre emphasized that the tremor posed no threat to Australia.

Papua New Guinea is located on the Pacific "ring of fire" which is a hot spot for seismic activities due to friction between tectonic plates.

Tracking back history, a huge tsunami caused by an undersea earthquake or landslide claimed the lives of more than 3500 people near Aitapi, an area on the northwest coast of mainland Papua New Guinea in 1997.

Meanwhile, at least 52 people were killed in the Solomon Islands died in 2007when a tsunami transpired after an 8.1-magnitude earthquake. Thousands of residents were left homeless too.
