A scientist gathers a sample of molten lava from a vent at the base of a new scoria cone in April 1976. Scientists from the Institute of Volcanology in Petropavlovsk analyzed lava samples throughout the eruption to determine the geochemical variation of eruptive products. The basaltic flow was one of several emplaced during a major SSW-flank eruption of Tolbachik in 1975-76. Photo by Oleg Volynets, 1976 (Institute of Volcanology, Petropavlovsk).
