Australia: The US Geological Survey reported that late Sunday a 7.0-magnitude earthquake struck just off the coast of the Pacific country of Vanuatu, causing a tsunami warning for the area.
According to the USGS, the shallow earthquake occurred around 11:30 p.m. local time (12:30 GMT) and was located around 27 kilometres (17 miles) away from the community of Port-Olry.
Vanuatu's coasts might see tsunami waves that are up to one metre above tide level, according to the NWS Pacific Tsunami Warning Centre in Hawaii.
New Caledonia and the Solomon Islands might experience waves that are smaller than 0.3 metres, it added.
Since tectonic plates meet in the Pacific "Ring of Fire," where Vanuatu is located, there is frequently seismic and volcanic activity there.
A large 7.0 earthquake struck the Solomon Islands in November, a neighbouring island nation to the north of Vanuatu, however there were no reports of catastrophic injuries or significant building damage.
Eyewitnesses described a severe shaking that sent objects flying and cut off power in certain areas of Honiara, the capital.
A tsunami warning for waves up to 30 centimetres tall was issued for the coastal areas of Vanuatu and the neighbouring country of Papua New Guinea (12 inches).
