The Pacific nation's government has ordered a mass evacuation of the island of Ambae, after about a week of escalating volcanic observations of Monaro Voui.
A state of emergency was declared on 26 September.
All 11,000 residents of Ambae - five percent of Vanuatu's population - have been told to evacuate the island.
Initially, islanders moved to shelters on Ambae but the government then ordered a mandatory island-wide evacuation. ■
