ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Sunday, January 8, 2023, 12:27 PM AKST (Sunday, January 8, 2023, 21:27 UTC)
Minor steam emissions were seen in clear web camera views during the last 24 hours. Satellite images were cloudy and no significant plumes were observed. Elevated seismicity has been occurring over the past day in the form of volcanic tremor. No noteworthy signals were detected in infrasound data.
Small eruptions producing minor ash deposits within the vicinity of the active north crater of Mount Young (formerly known as Mount Cerberus) 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.
Lava likely continued to erupt in the summit crater of Great Sitkin Volcano over the past day. Weakly elevated surface temperatures were observed once in partly cloudy to cloudy satellite images. Web camera views were obscured by clouds. A few small local earthquakes were detected at Great Sitkin during the last 24 hours.
Great Sitkin Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.
No eruptive activity observed. Weakly elevated surface temperatures were observed twice in partly cloudy to mostly clear satellite images over the past day. Web camera views were clear but showed nothing of note. Occasional small low frequency events were detected in seismic data during the last 24 hours.
Small explosions associated with the current eruption could happen at any time and may be accompanied by small ash plumes within the immediate vicinity of the volcano. The level of unrest at Pavlof Volcano can change quickly and the progression to more significant eruptive activity can occur with little or no warning.
Pavlof Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.
The ongoing swarm near Takawangha volcano continued over the past day, but at a reduced rate compared to previous days. This activity may be due to the movement of magma beneath the volcano. No other signs of unrest were observed in cloudy satellite images.
