Description: From Reeder (1990): "During 1987, nearly continuous minor steam emissions occurred from the tephra cone in the Akutan summit caldera. Between 31 January and 24 June, numerous tephra emissions occurred from the caldera cone, causing it to increase in height by about an estimated 100 m." The highest tephra plume went to 4,900 m on February 10, 1987. Ash plumes were often observed by pilots and by residents of Akutan. Incandescence was observed on the evening of April 22 (+/- 1 day). See Reeder (1990) for detailed observations and chronology.
