From McGimsey and others (2003): "On November 4, 1998, AVO received word from the U.S. Coast Guard (USCG) of a possible ash plume above the summit crater of Shishaldin Volcano. The report reads, 'Ash and smoke extending up to 100 ft above volcano vent; dark in color. Puffs approximately 10 minutes apart.' This type of activity is typical of Shishaldin and probably reflects a continuing high-level heat source and intermittent phreatic explosive activity within the summit crater."
