Description: From Shackelford (1979): "Sporadic ash eruptions, which began in fall 1976, were still continuing as of May 1977. Observations of the activity during May 1977 showed explosive ejection of light brown ash clouds (every 1/4 hour between 17:00 and 20:00 on 5 May) with the ash cloud drifting N. During the inter-eruption periods, white fume emission occurred. Incandescent tephra was noted on 6 May at 17:30, and further eruptions were noted the following day. Similar activity was noted on 9 May. It is not unlikely that this explosive activity continued beyond the last date of observed activity, as Akutan typically is in a state of mild explosive activity lasting months or years. No further information known to this reporter."
