Event Type: Explosive
Max VEI: 1 [2]
Description: From Neal and others (1996): "On September 14, National Wildlife Service (NWS) relayed three pilot reports of sulfur smell northwest of Dutch Harbor and one veteran pilot report of "a trace of ash" at 4000 feet. Subsequent investigation turned up the fact that, over the past month, pilots had frequently smelled sulfur and seen "smoke and steam" from Makushin, as well as snow apparently darkened by ash. A similar report was called into AVO on September 23. On November 5, 1993, AVO received a report from NWS relaying a USCG cutter sighting of eruptive activity at 0930 Aleutian Standard Time. AVO and NWS examined available satellite imagery and found no anomaly; calls to residents of Dutch Harbor/Unalaska confirmed no ashfall. A NOTAM was issued by NWS. As phreatic activity is typical at Makushin, AVO distributed no formal information releases at any time."
