Mount Yasur’s Eruptive History

? Mount Yasur has been erupting continuously for at least hundreds of years. Captain Cook was attracted to the Island’s glow during his voyage in 1774.
2000 Lake Siwi was at the base of Mount Yasur. In 2000, the lake drained after a collapse of the natural dam.
2016 Extreme Pursuit visited during a Level 2 and Level 3 alert. Large strombolian eruptions and ash plumes were observed. Some lava bombs were expelled outside of the crater.
2018 Our second visit. Large strombolian eruptions were observed, however not to the extent of the 2016 eruptions. Small ash clouds were produced.
2019 Semi-persistent lava lake. Strombolian eruptions and crater wall collapses observed.
2022 Extreme Pursuit visited again and noted extremely large ash eruptions. Lava/strombolian activity was present, but mostly obscured by the ash.
2023 Extreme Pursuit expedition. Vents A, B and C are all active. A is the most violent, producing strombolian eruptions every 2-3 minutes. There is an active lava lake in vent C that erupts every 15 minutes or so.
2024 Regular strombolian eruptions continue.
