A phase of explosive activity began December 8 at 13h local / 03h UTC at Manam volcano in Papua New Guinea.
The ash and gas plume rose more than 13.5 km, drifting east and northeast. Strong ashfall on the island is reported by observers (planes and US Navy ship), blocking the sun's rays and hiding the volcano's summit.
According to VAAC Darwin, the plume should dissipate within three hours.

An eruption occurred this December 8 at 9:12 local at Dukono volcano in the Moluccas. An ash plume developed to a height of 1529 meters asl. The eruption continues.
VAAC Darwin plans to ashes move west and then southwest.
An orange VONA has been issued and the activity level is 2 / waspada, with a 2 km radius ban around the Malupang Warirang crater. Ashes can fall on the island, a mask protection is recommended.
