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.
