Description: From the Smithsonian Institution (1996): "On 27 September the Aviation Weather Unit in Alaska received a pilot report of a minor eruption of ash and steam at Gareloi. The plume reportedly rose to 1,500 m altitude but was not visible on infrared satellite imagery suggesting it may have not ascended that high. As late as 5 December AVO had learned of no further sightings of activity at Gareloi."
