The Alaska Volcano Observatory (AVO) recorded highly elevated surface temperatures identified in satellite data which relate to active lava flows on the SE flank. Satellite-based radar views showed a widening of the vent and possible lava flows towards the east.
"Periods of lava fountaining from the vent on the volcano's upper southeast flank have been occurring since mid-November 2021. This activity has built a small cone and sent flows down the flank that melt the snow and ice and produce variable amounts of meltwater. The meltwater typically incorporates loose debris on the flank of the volcano and forms thin (
