Nine earthquakes strike off Vanuatu as tsunami warning lifted

UPDATE – 5.46pm NZT, Saturday 24 October

Three more earthquakes have struck off northern Vanuatu within 14 minutes, as seismic activity continues following Saturday's powerful magnitude 6.9 earthquake.

The United States Geological Survey records tremors measuring magnitude 5.7, 5.8 and 5.3 between 5.05pm and 5.19pm New Zealand time, all at a depth of 10 kilometres.

At least nine earthquakes ranging from magnitude 4.5 to 6.9 have now been recorded in the region on Saturday.

Vanuatu authorities earlier cancelled a tsunami warning following the initial earthquake, but the seismic activity continues.

UPDATE - 5.19pm NZT, Saturday 24 October

Vanuatu's Geological Hazards Department has cancelled its tsunami warning following a series of powerful earthquakes off the country's northern coast.

In a statement on Facebook, the department says the latest sea-level observations confirm there is no longer a tsunami threat to coastal communities.

Meanwhile, the United States Geological Survey has recorded another magnitude 4.9 earthquake at 4.51pm New Zealand time, bringing the number of tremors recorded near Port-Olry on Saturday to six.

The strongest, measuring magnitude 6.9, struck at 3.31pm NZ time, followed by a magnitude 6.3 earthquake four minutes later. Four other tremors ranging from magnitude 4.5 to 5.2 have also been recorded.

UPDATE - 4.49pm NZT, Saturday 24 October

The United States Geological Survey now lists five earthquakes off northern Vanuatu on Saturday afternoon, ranging from magnitude 4.5 to 6.9.

A magnitude 4.5 tremor was recorded at 1.27pm NZ time, followed by a magnitude 6.9 earthquake at 3.31pm and three further earthquakes measuring 6.3, 5.1 and 5.2.

The latest recorded event struck at 4.17pm NZ time.

UPDATE – 4.30pm NZT, Saturday 24 October

The United States Geological Survey has recorded three further earthquakes off northern Vanuatu following Saturday's magnitude 6.9 tremor.

The subsequent earthquakes measure 6.3, 5.1 and 5.2, all at a reported depth of 10 kilometres.

All four earthquakes have been recorded within 47 minutes, northwest of Port-Olry.

UPDATE – 3.55pm NZT, Saturday 24 October

A magnitude 6.9 earthquake has struck off northern Vanuatu, just four days after another powerful tremor hit the region.

The United States Geological Survey says the earthquake struck at a depth of 10 kilometres, about 197 kilometres west-northwest of Port-Olry, shortly after 1.30pm local time on Saturday.

Initially reported at magnitude 7.2, the earthquake has since been revised to 6.9.

The Pacific Tsunami Warning Center initially warned that hazardous tsunami waves were possible along Vanuatu's coastline within 300 kilometres of the epicentre.

There are no confirmed reports of damage or casualties at this stage.

This comes only days after a magnitude 6.3 earthquake struck off the coast of Vanuatu on Tuesday, sparking initial concern before disaster management agencies confirmed there was no threat of a tsunami to surrounding Pacific communities.

The undersea tremor hit at a depth of 10 kilometres in the ocean waters northwest of Port Olry, a village on the northern island of Espiritu Santo.

The Pacific Tsunami Warning Centre acted quickly to reassure local authorities and coastal families, issuing a clear clearance following the event.
