A large explosive eruption occurred at Manam volcano Friday, sending an ash plume 11 km (34,000 ft) above sea level, the Darwin VAAC reported.
The volcanic ash cloud is moving west over mainland Papua New Guinea, rapidly weakening as it goes.
The Aviation Color Code has been raised from Orange to Red.
Similar eruptions have been occurring in the past weeks, most notably on Aug 24 and Sep 23.
On Aug 24, an explosive eruption produced a similar ash plume to approx. 15 km (50,000 feet) a.s.l. and lava flows that forced 2000 inhabitants of the small island to flee.
According to a newspaper article, “islanders reported ash and other debris from the volcano was so thick that sunlight was totally blocked for a few hours.”
