A volcanologist from the Institute of Volcanology in Petropavlovsk, shielded from the intense heat in a reflective suit, extracts a glowing sample of lava from a flank vent of Klyuchevskoy volcano in 1983. Geochemical analysis of lava samples is used to understand the eruption dynamics and the magmatic history of the volcano. Eruptions of flank and summit lava flows are common here. Protective clothing is always needed when working on active volcanoes, but sampling at lava flows such as this is rare.
