54°45'19" N 163°58'16" W,
Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Low-level eruptive activity continues. AVO has received a pilot report this morning of a low-level steam and possible ash plume from Shishaldin. Sound waves are currently being detected from the direction of Shishaldin on infrasound sensors located at Dillingham and on Akutan Island. These signals are consistent with low-level activity at the volcano. Satellite and web camera views are obscured by weather. No significant activity noted in seismic data.

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.
