Volcanic Alert Bulletins

Volcano Alert Bulletins (VABs) are New Zealand's official source of volcano status information including the current Volcanic Alert Level (VAL). They are issued on an as needed basis summarising the volcano status and recent events. They can indicate if activity is increasing, decreasing, or in a steady state. They may contain forecasts, highlight developing, or expected problems.
If you’d like to be notified as soon as we issue a new bulletin, our social media channels and the GeoNet app will keep you up-to-date.

Mt Ruapehu: Crater Lake heated to 40°C

Crater Lake (Te Wai ā-moe) has been heating in response to an input of hot gases and hydrothermal fluids following volcanic earthquakes beneath Mt Ruapehu in February. The lake temperature is now 40°C. GNS Science volcanologists have collected further data to understand current activity.

Whakaari/White Island eruption: Update #18

Whakaari/White Island remains in an elevated state of unrest. Very hot gas and steam continue to discharge from the December 9th vents. Further eruptions over 24 hours on any given day are very unlikely in the next four weeks. The Volcanic Alert Level remains at Level 2. The Aviation Colour Code changes to Yellow as ash only rarely gets emitted at the vent.
