NOUMEA: A shallow and strong 7.5-magnitude earthquake struck off New Caledonia Wednesday prompting a tsunami alert and evacuations on the Pacific island, authorities said.
Pacific Tsunami Warning Centre said that tsunami waves had been “observed” in region but did not say where.
Residents of New Caledonia, which lies north of New Zealand, received text messages handle them to go to refuges immediately, with waves of up to three metres possible, according to the warning centre.
But people in New Caledonia and nearby Vanuatu said they did not feel quake, and tsunami warning sirens were not immediately activated in Vanuatu.
“Hazardous tsunami waves are forecast for some coasts,” the Pacific Tsunami Warning Center said, after earlier warning that danger zone included “coasts located within 1000 kilometres of the earthquake epicentre.”
The epicentre was 300 kilometres east of Noumea.
Various aftershocks were reported as the tsunami centre warned of waves of up to three metres above tidal levels for New Caledonia and Vanuatu and up to one metre for some parts of Fiji.
New Zealand authorities issued a similar tsunami warning after quake, but that was immediately rescinded.
There were no immediate reports of damage from the initial earthquake and according to US Geological Survey modelling, damage from the quake is expected to be minimal in terms of loss of life.
