1367 PAPUA NEW GUINEA (East New Britain) - Tavurvur volcano

Tavurvur is an active stratovolcano that lies near Rabaul, on the island of New Britain, the largest island in the Bismarck Archipelago. It is a sub-vent of the Rabaul caldera and lies on the eastern rim of the larger feature. An eruption of the volcano largely destroyed the nearby town of Rabaul in 1994. It is the most active volcano in Rabaul caldera, and the latest eruption began on 29 August 2014, prompting concerns over disruption of flights in Australian airspace due to the large ash clouds. Communities near the volcano were evacuated, while residents of the town of Rabaul were advised to remain indoors to avoid falling ash.
