Activity remains dynamic at Papua New Guinea's Manam volcano after another eruption at the weekend.
PNG's Volcanological Observatory said Saturday's eruption ejected dark grey ash plumes an estimated two kms high.
Frequent projections of lava fragments into the air were recorded, as was audible rumbling.
Blown southeast, the ash plumes caused ashfall on villages between Boakure and Warisi in Madang on the north coast of PNG's mainland.
The eruption had now ended but the fact that three had occurred on Manam within four months suggested the volcanic system was still dynamic and volatile, the observatory said.
The potential for further eruptive activity in the future is high, it said.
