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.

Continued heat flow and changes in gas composition indicate increased unrest at Whakaari/White Island. Volcanic Alert Level raised to Level 2.

Persistent observations of night glow on the web cameras indicate continued emission of high-temperature gases. Continued decline of the carbon dioxide to sulphur dioxide ratio points to ongoing degassing of fresh magma. The Volcanic Alert Level has been raised to 2 and the Aviation Colour Code to Yellow. This also acknowledges the uncertainty about what is driving current activity at the volcano.

Increased heat flow confirms ongoing volcanic unrest at Whakaari/White Island

An observation and thermal infrared (IR) measurement flight has confirmed high temperatures are again present. These are from locations on the 2019 lava extrusions where high temperatures have been recorded before. These observations confirm the source of glow on the web cameras. There is no evidence of eruptive activity. The Volcanic Alert Level remains at 1.

Further minor tremor and steam bursts, explosions

Two short-lived episodes of low-energy volcanic tremor occurred on 11 and 12 March at Whakaari/White Island, following similar episodes in mid-February and early March. Since then activity has returned to typical low-levels. The Volcanic Alert Level remains at 1.

Minor steam explosions at Whakaari/White Island

A series of short-lived, low-energy steam explosions occurred on 19 February 2021 at Whakaari / White Island following a small increase in volcanic tremor levels. These explosions took place over about 100 minutes. These small events do not appear to have produced any traces of ash locally. Since the event, activity has returned to low-level. The Volcanic Alert Level remains at 1.

Year-long monitoring reveals declining vent temperatures at Whakaari/White Island

Remote monitoring of the vent area at Whakaari / White Island that erupted in December 2019 has revealed that the temperatures of gas emissions has declined from over 700 oC to 300 oC in the last year. Recent observations suggest no eruptive activity since a series of minor steam explosions on 29 December 2020. Current activity is still characterised by steam and gas emissions at moderate-low levels. The Volcanic Alert Level remains at 1.

Small steam explosions recorded at Whakaari/White Island

A series of short-lived, low energy steam explosions occurred on 29 December 2020 at Whakaari / White Island over a period of ~ 30 mins. This small event consisted of at least 20 individual pulses and may have produced traces of ash locally in the steam plume for a few minutes. Since the event, activity has returned to low-level. The Volcanic Alert Level remains at 1.

Last year

Ash emission has stopped at Whakaari/White Island. Volcanic Alert Level is lowered to Level 1.

Observations in the last week show that ash is no longer being emitted from Whakaari. Levels of gas emission have also decreased, and other monitoring indicators remain low. The Volcanic Alert Level is lowered to Level 1.

Last year

Ash emission has reduced at Whakaari/White Island. Volcanic Alert Level remains at Level 2.

Camera images from Whakaari/White Island appear to show that ash is no longer present in the near-persistent steam and gas plume. The amounts of CO2 and SO2 gas remain elevated. The Volcanic Alert Level remains at Level 2.
