Ugashik-Peulik volcano (United States) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 April-20 April 2021 (Continuing Activity)
AVO reported a loss of operation and communication with seismic stations that monitor Ugashik-Peulik, likely caused by snow cover. Both the Aviation Color Code and the Volcano Alert Level were changed to Unassigned on 19 April, reflecting the inability to locate earthquakes to detect unrest. Monitoring will continue with the remaining seismic stations, regional infrasound networks, lightning detection, and satellite images.
