The Red Cross in Madang Province in Papua New Guinea says locals are still on alert for further possible eruptions on Manam Island.
An earlier volcanic eruption saw lava flows and volcanic dust affect villagers on the island on October 24th.
But the Chairperson of the Red Cross, Maureen Hill, says another eruption last Sunday has seen more lava flowing further down the mountain.
"Eventually if it keeps going, it'll put at risk a number of villagers, in particular Bockure. But people have been warned, and there are evacuation plans in place."
Maureen Hill says they are working with organisations like World Vision to give out food and shelter supplies to help around two thousand affected people.
She says water is no longer a problem in the area, following recent rainfalls.
