Steam rises from the margins of an active lava flow from a SW-flank vent of Klyuchevskoy in 1974. Renewed summit crater explosive activity began 8 April, with lava fountaining beginning 18 May. Increasing seismicity preceded the 23 August outbreak from 3,400-3,600 m elevation on the SW flank. Lava effusion continued until December. Photo by I.T.
