Another eruption has been recorded at Papua New Guinea's Manam volcano.
The Volcanic Ash Advisory Center in Darwin reported an explosion at Manam that generated an ash plume reaching approximately 3000 metres high.
Manam, a volcanic island located 12km off New Guinea's north coast, last erupted in November last year.
A series of eruptions over the past 15 years has forced many people from the island to mainland PNG.
Displaced Manam Islanders continue to struggle for resettlement on the mainland.
