White Island (Antarctica): (3 Apr) The most recent airborne gas measurements from 26 March indicate a slight uptick in sulfur dioxide (SO2) levels compared to measurements taken a month earlier on 29 February 29. Although there has been a slight upward trajectory in SO2 emissions over the past year, the overall emissions of the key monitored gases – carbon dioxide (CO2), hydrogen sulphide (H2S), and SO2 – remain at low to moderate levels.
Observation flights on 20 March captured images showing minor geyser activity in certain parts of the crater region, caused by the continuous release of steam and gas through muddy pools. These emissions result in the formation of sulphur and other salt deposits. The grey and green hues in the pools and lake are primarily due to dissolved sulfur combined with suspended sediments, characteristic of the volcano. Occasional steam and gas plumes above the island can be seen from the coast, particularly during cool and relatively calm weather conditions.
