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 is experiencing moderate volcanic unrest and the Volcanic Alert Level is raised to Level 2.
Another earthquake swarm started near Whakaari/White Island at around 4 am Thursday morning, 20 June 2019.
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.
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.
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.
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.
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.
The Crater Lake at White Island continues to grow, which may cause hydrothermal surface activity. The Volcanic Alert Level remains at 1.
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.
Observations during visits to White Island and from the web cameras confirm that the crater lake is starting to reform and volcanic activity remains at low levels.
