About 130 km (81 mi) southwest of the township of Rabaul, Ulawun is the highest mountain in New Britain and the second in the Bismarck Archipelago at 2,334 metres (7,657 ft), and one of the most active volcanoes in Papua New Guinea. A total of 22 recorded eruptions have occurred since the 18th century; the first, in 1700, was recorded by William Dampier. Several thousand people live near the volcano. Because of its eruptive history and proximity to populated areas, Ulawun has been deemed one of the Decade Volcanoes.

Recent activity

The last few years have seen almost constant activity at Ulawun, with frequent small explosions, and have caused great damage and loss of life. the New Britain Highway in three different locations.[2]

Volcanoes in Papua New Guinea are some of the world's most prolific sources of sulphur dioxide. Recent studies have shown that Ulawun alone releases about 7 kg/s of SO₂, which is about 2% of the global total of SO₂ emissions into the atmosphere.

Ulawun has been named one of the Decade Volcanoes, 16 volcanoes identified as being worthy of particular study in light of their history of large, destructive eruptions and their proximity to populated areas. By Abubakr Sattar
