On 18 October GeoNet reported results from a recent overflight of Whakaari/White Island. Gas measurements showed that sulfur dioxide emissions had decreased from 520 tons per day recorded at the end of September to 267 tons per day. Temperatures in the main vent area were as high as 220 degrees Celsius, similar to temperatures measure two weeks prior.Minor ash deposits from intermittent ash emissions were visible in the area close to the active vents. Seismicity was characterized by low levels of volcanic tremor and occasional low-frequency volcanic earthquakes. The Volcanic Alert Level remained at 2 and the Aviation Color Code remained at Yellow.

On 27 September GeoNet reported results from an overflight of Whakaari/White Island the previous week. Gas measurements showed that sulfur dioxide emissions had increased to 680 tons per day from 450 tons per day recorded in mid-August, continuing the trend of an increasing emission rate noted over the past few months. The gas data suggested magma input deeper in the system. ... Read all
