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.


Whakaari/White Island: Volcanic unrest continues with steam and mud discharge, decreased gas emissions, steady vent temperatures and lake level fall

Recent gas and observation flights at Whakaari/White Island show a decrease in gas emissions and lake level. The vent temperatures remain steady around 240-260 °C. The volcano continues to emit traces of volcanic ash, and the effects on the ground of a small, but energetic discharge of steam and mud were observed. A state of moderate to heightened unrest continues. The Volcanic Alert Level remains at Level 2

Whakaari/White Island: Intermittent weak ash emissions continue

Intermittent ash emissions continued last week, and further occasional emissions are expected to occur in the coming weeks. Small amounts of ash were carried by the vigorous degassing a few hundred metres into the atmosphere near the volcano, and further activity of this type is unlikely to affect the mainland. The volcano remains in a state of moderate to heightened unrest and the Volcanic Alert Level remains at Level 2.
