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.
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.
Observations from a visit to White Island on Wednesday suggest that the minor ash emission that occurred on Tuesday 13 September 2016 has ceased. The Volcanic Alert Level is lowered to 2, and the Aviation Colour code is lowered to Yellow.
Monitoring data available from the island confirms there has been no escalation in the level of activity and the emission of ash is currently very minor.
As far we can tell from our monitoring data there has been no escalation in the level of activity at White Island since late morning. Seismic activity remains low on the island. Some of our cameras are now been affected by ash and steam, so we may not see much from them in the short term.
The level of volcanic activity at White Island has increased late this morning with minor volcanic ash been passively emitted from a vent on the 2012 lava dome. A report from the island at 11.50h has confirmed the ash emission.
The level of volcanic unrest at White Island declined following the eruption. Volcano seismic activity has decreased, while the gas output has been variable and is now at typical background levels. No further eruptions have occurred and the Volcanic Alert Level remains at Level 1.
