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. 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
