Seismic activity is elevated at Semisopochnoi volcano, with small earthquakes detected over the past day. Web camera images show low-level degassing from the active crater.
Small eruptions producing minor ash deposits within the vicinity of the active north crater of Mount Young and ash clouds usually under 10,000 ft (3 km) above sea level have characterized the recent activity. Additional ash-producing events could occur again with little warning.
Semisopochnoi volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.
Seismicity remained low at Great Sitkin Volcano over the past 24 hours and only a few small earthquakes were detected. No activity was observed in satelllite or web camera views of the volcano.
Great Sitkin Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.
Numerous small, local earthquakes were detected at Takawangha volcano over the past day. No signs of unrest were seen in cloudy satellite views of the volcano.
Takawangha volcano is monitored by local seismic and infrasound sensors, satellite data, and regional infrasound and lightning networks.
