From January to March 1983 a number of small ash eruptions occurred; in mid-February there was a slight fall of fine grey ash at Olduvai Gorge, 65 km to the west.

John Fanshawe and Harvey Croze took photographs from the air in early April 1983; [see web site] There was a lava flow reaching about two thirds across the floor of the pit crater and two small black cones with open vents at the base of the north wall.
