From Neal and others (2011): "AVO received a number of calls during 2008 regarding possible steam and ash emissions from Shishaldin. The first caller on January 8 reported a plume rising just a few thousand feet above the summit. On February 11, AVO received word from the National Weather Service of several pilot reports of a plume containing ash to an estimated 15,000 ft (4,600 m) ASL and extending south for about 25 mi (40 km). A check of seismicity showed nothing unusual that would reflect an increase in activity or ash emission. A one-time SIGMET was issued by National Weather Service. The following day, the USCG inquired about the status of the volcano and its potential for impacting operations in the area."
