This was the second time this year the students have had to be evacuated.
The Vanuatu Daily Post reports all senior students have already been relocated to schools on Maewo Island and Santo.
The government has determined that Ambae is no longer safe for the up to 11,000 people that continue to live there.
Police are expected to be assigned to travel to Ambae soon to assist with the relocation.
Meanwhile, concerns have been raised about students' living conditions on the two islands.
