Saturday, August 31, 2024, 11:32 AM AKDT (Saturday, August 31, 2024, 19:32 UTC)
Lava continues to slowly erupt at Great Sitkin Volcano, feeding a thick lava flow that is gradually filling the summit crater. Small earthquakes continued to be detected beneath the volcano. Weakly elevated surface temperatures from the active lava flow surface were observed in satellite data today.
The current lava flow eruption began in July 2021. No explosive events have occurred since a single event in May 2021.
Local seismic and infrasound sensors and web cameras are used to monitor Great Sitkin along with regional infrasound and lightning networks and satellite data.
