Following renewed explosive activity in the Klyuchevskoy summit crater starting on 8 April 1974, an eruption began on 23 August from a vent on the SW flank. This was the highest flank vent location to date in Klyuchevskoy’s recorded history. This photo shows lava fountaining and effusion of a lava flow from the SW-flank vent. The eruption continued until the end of the year. Photo by N. Smelov, 1974 (Institute of Volcanology, Petropavlovsk).
