GREAT SITKIN (VNUM #311120)

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Lava continues to erupt at Great Sitkin Volcano. The current eruption is feeding a thick lava flow that is gradually filling the summit crater. The local seismic network continues to detect small earthquakes and rockfall signals caused by ongoing lava eruption. Satellite views have been cloudy over the last day.
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.
