ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Wednesday, November 26, 2014, 11:38 AM AKST (Wednesday, November 26, 2014, 20:38 UTC)
55°25'2" N 161°53'37" W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Seismicity at the volcano has remained at low levels over the past 24 hours. Thermal features at the summit are occasionally visible in satellite data, but are likely being generated by the cooling of previously emplaced lava and debris and not newly erupted material.
Pauses in vigorous eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to more robust eruptive activity remains possible and could occur with little or no warning.
54°45'19" N 163°58'16" W,
Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Seismic activity has remained elevated and steady over the past 24 hours. No ash plumes have been observed or detected in satellite images. When the volcano summit is not obscured by clouds, strongly elevated surface temperatures have been evident. The level of seismic activity and thermal features suggest that a low-level lava eruption continues within the summit crater of the volcano.
OTHER ALASKA VOLCANOES
Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
