54°45'19" N 163°58'16" W,
Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Elevated surface temperatures at the summit of Shishaldin Volcano were observed in clear satellite images over the past 24 hours. Periodic low-level steam emissions are visible in some web camera views, and this morning an image showed a wispy, low-level ash emission from the summit drifting west-southwest. Seismicity remains above background levels. Low-level eruptive activity confined to the summit crater of the volcano likely continues.

Nothing of note has been observed in satellite data over the past 24 hours. No significant activity has been detected in seismic or infrasound (air pressure) data.
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.
