Ulawun is a basaltic and andesitic stratovolcano situated on the island of New Britain, in West New Britain Province, Papua New Guinea.

It is about 130 km south-west of Rabaul. It is the highest mountain in the Bismarck Archipelago at 2,334 metres (7,657 ft), and one of the most active volcanoes in Papua New Guinea. The first recorded eruption of Ulawun was by William Dampier in 1700; there have been 22 recorded eruptions since the 18th century. Several thousand people live near the volcano.

Recent activity

A steam plume over the sea from the Ulawun is clearly visible on this satellite image.

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.

It is a mud form and is rock which leads magma upwards due to magma and the eruptions

Decade Map

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.
