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.
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.
The Crater Lake at White Island continues to grow, which may cause hydrothermal surface activity. 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.
Observations during visits to White Island over the last 3-4 months confirm that activity remains at low levels. Activity is confined to the gas rich vents on the western side of the active crater. Hot, clear gas continues to be emitted. Some water has ponded on the floor of the active crater but no permanent lake has reformed. The seismic and acoustic activity generally remain low, and the SO2 gas flux is slowly declining.
Observations during a visit to White Island on Friday have confirmed that a large part of the gas is now being emitted from one ‘joint’ vent on the lava outcrop at the back of the crater. The joining of the vents has resulted in a stronger and noisier gas flow from this vent. The temperature has declined slightly, it is now only 250 °C, down from 300 °C.
No further sustained eruptive activity has been observed at White Island. As a consequence the Volcanic Alert Level has been lowered to Level 1. The Aviation Colour code remains Yellow.
