The volcano - known as Monaro - has been rumbling for weeks, but its activity increased rapidly on Saturday, when it started belching ash across much of the island, blanketing villages and crops in the north and south.
That prompted authorities to evacuate half the island's population - at least 5000 people - from the north and south of the island, sending them to the east and west.
"It's quite a serious emergency," said Manuel Amu, the chairman of the island's disaster committee. "Moving people from their communities into an area with very limited houses and very limited resources like food and water. It's really a challenging issue.
"At the moment the volcano has blown up ash and dark smoke, with a little bit of lava," he said in an interview.
