7.7-magnitude earthquake strikes in South Pacific
A 7.7-magnitude earthquake that struck in the South Pacific has generated a tsunami, the Australian weather agency said on Thursday.
“Tsunami confirmed,” the Australian Bureau of Meteorology said in a tweet, as it warned of a threat to Lord Howe Island, which is about 550 kilometres (340 miles) east of Australia’s mainland.
The quake struck at just after midnight today local time (1320 GMT Wednesday) about 415 kilometres (258 miles) east of Vao in New Caledonia at a depth of 10 kilometres, according to USGS.
“Hazardous tsunami waves from this earthquake are possible within the next three hours,” the NWS Pacific Tsunami Warning Center said.
Waves reaching between 0.3 and one metre above the tide level are possible for some coasts of Fiji, New Zealand and Vanuatu, the centre said.
Smaller waves were forecast for other nations in the region including Australia, the Cook Islands and American Samoa.
There were no initial reports of casualties or damage from the quake, which was initially recorded by USGS at magnitude 7.5 before being revised to 7.7.
The Pacific “Ring of Fire”, where tectonic plates collide, experiences frequent seismic and volcanic activity.
