Whakaari/White Island volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 September-28 September 2021 (Continuing Activity)
Wed, 22 Sep 2021, 06:00
06:00 AM | BY: VNTemperatures in the main vent area notably decreased to 189 degrees Celsius from July and August measurements of 650 degrees, possibly indicating cooling caused by groundwater infiltration. Minor ash deposits from recent emissions were visible around the active vents. Seismicity was characterized by low levels of volcanic tremor and occasional low-frequency volcanic earthquakes.
Subsidence continued to be measured by satellite. The Volcanic Alert Level remained at 2 and the Aviation Color Code remained at Yellow.

Whakaari/White Island volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 September-14 September 2021 (New Activity / Unrest)
On 14 September GeoNet reported that intermittent ash emissions at Whakaari/White Island continued to be visible during the previous week. Vigorous fumarolic plumes from the active vent area sometimes carried minor amounts of ash downwind at low altitudes and occasionally deposited ash on the island. Periods where ash was visible in the emissions did not correspond to explosive seismic or acoustic signals, suggesting that the ash was produced by weak wall fragments falling into the gas stream through the active vents and not from eruptive activity. ...
