Lava continues to erupt slowly at Great Sitkin Volcano. Ongoing activity is adding to a thick lava flow that fills most of the summit crater. Small earthquakes associated with the ongoing lava eruption continue. Satellite and web camera images were mostly obscured by clouds over the past day.

A single explosive event occurred in May 2021 and was followed by the ongoing eruption of lava that began in July 2021. No explosive events have occurred since 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.
