The quake hit about 200km (125 miles) south-west of the town of Rabaul at a depth of almost 40km. There were no immediate reports of damage or injuries. The Pacific Tsunami Warning Centre said waves less than 30cm high could be expected on coastlines in Papua New Guinea and neighbouring Solomon Islands. Australia’s Tsunami Warning Centre said its coastlines were not at risk. Some tourists and residents ducked outdoors as a precaution but then went back to sleep when there was no tsunami warning. A Pacific-wide tsunami is not expected and there is no tsunami threat to Hawaii. Papua New Guinea sits on the geologically active Pacific ring of fire. The country is is still recovering from a magnitude-7.5 earthquake that hit around 900km to the west.
A statement from the PTWC reads: “Government agencies responsible for threatened areas should take action to inform and instruct any coastal populations at risk in accordance with their own evaluation. The island of Bali was also struck by a magnitude 6 earthquake on Thursday, the US Geological Survey said. The annual meetings of the International Monetary Fund and World Bank are being held this week in Bali and attended by more than 19,000 delegates and other guests, including ministers, central bank heads and some leaders.
