Ulawun

Ulawun

Ulawun is a volcano situated on the island of New Britain, Papua New Guinea, about 130 km southwest of Rabaul. It is the highest mountain in the Bismarck Archipelago, and one of the most active volcanoes in Papua New Guinea. Several thousand people live near the volcano.

Recent activity

The last few years have seen almost constant activity at Ulawun, with frequent small explosions.

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