Tsunami Warning After New Caledonia Earthquake
An undersea earthquake of magnitude 7.0 has struck 82km east of New Caledonia's Loyalty Islands, prompting a tsunami warning for coastlines within 300km of the epicentre.
The quake, initially reported as magnitude 7.3, is the second major tremor in the same area in less than 24 hours and the third in the past month.
Monday's quake struck at 9.43am local time at a shallow depth of 10km, east of the remote Loyalty Islands, the United States Geological Survey says.
The Pacific Tsunami Warning Centre said hazardous tsunami waves were possible along the coastlines of New Caledonia and Vanuatu.
"Government agencies responsible for threatened coastal areas should take action to inform and instruct any coastal populations populations at risk," the PTWC said in an alert.
Australia and New Zealand do not face any tsunami threats, authorities say.
