New radar satellite data yesterday show that lava continues to erupt at Great Sitkin Volcano. Current lava eruption is feeding a thick lava flow that is gradually filling the summit crater. Small earthquakes beneath the volcano continued to be detected.
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.
