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.

Earthquake activity near Whakaari/White Island decreases
The earthquake swarm near Whakaari/White Island which started May 23 continues but has decreased in intensity and numbers. The swarm has not resulted in any increase in volcanic activity or landsliding on island.
Local earthquake swarm near Whakaari/White Island
A local earthquake swarm near Whakaari/White Island started on Thursday. Over the past 24 hours the rate and magnitude of earthquakes has increased. The swarm does not appear to be linked to volcanic unrest but may result in increased landslide risk on island.
Te Wai ā-moe, Mt Ruapehu crater lake is starting to cool and seismic activity decreases.
The period of high lake temperatures at Te Wai ā-moe (Crater Lake), Mt Ruapehu along with moderate levels of volcanic tremor has now passed. We are now moving away from a range of higher probability of eruption in this heating phase. The Volcanic Alert Level remains at 1.
Whakaari/White Island crater lake level drops and is unlikely to overflow
As at April 13, 2019 the crater lake is about 13 metres below overflow, which is 2 metres lower than the peak level reached earlier this year in January.
Te Wai ā-moe, Mt Ruapehu: Increases in lake temperature and seismic activity
We are recording another phase of high lake temperatures at Te Wai ā-moe (Crater Lake), Mt Ruapehu along with moderate levels of volcanic tremor. The Volcanic Alert Level remains at 1.
White Island (Whakaari): Rising Crater Lake may cause hydrothermal surface activity
The Crater Lake at White Island continues to grow, which may cause hydrothermal surface activity. The Volcanic Alert Level remains at 1.
A new heating cycle begins at Mt Ruapehu
Te Wai ā-moe (Crater Lake) temperature at Mt Ruapehu is rising along with an increase in volcanic tremor. This is consistent with minor volcanic unrest behaviour. The Volcanic Alert Level remains at 1.
