About 3500 evacuees arrived on the island of Espiritu Santo overnight, bringing the total number of evacuees close to 5000, with up to 4000 more still to leave Ambae.
Provincial officials said the 19 evacuation centres on Santo were already filled to capacity and about 1000 evacuees have yet to be processed.
The government wants the entire population evacuated by Friday, but officials said the original figure of 11,000 given for Ambae's total population could be too low.
