One of the major challenges faced by authorities is managing the evacuees and their water and food supply.
More than 7000 residents have been relocated from the danger zones to safe zones on the east and west sides of the island.
Vanuatu Red Cross Disaster Risk Reduction coordinator, Agustine Karae, says over 50 evacuation centres have been opened in the two areas.
“Schools and community centres have been opened up as evacuation centres on the island of Ambae. There are 30 centres on the east of the island alone,” he said.
