Event Type: Other

Event Characteristics:

Steam ^[1]

Description: From Reeder (1987): "Pilot Tom Madsen observed the emission of voluminous amounts of steam from the summit crater of Amukta volcano of Amukta Island during a return trip from Atka of Atka Island to Dutch Harbor of Unalaska Island. His observation was made at about 1600 local time on 12 July 1984. The steam plume completely filled the summit crater, rose to a 1,100 m altitude just above the volcano, and drifted to the SW for at least 4 km at a lower altitude. Tom Madsen has flown in the Aleutian Islands since 1980 and he has only observed occasional wisps of white steam from this crater before. This steam activity was considered by Tom to be very anomalous."
