This false-color satellite image shows the two volcanoes on November 5, 2010. Diminutive steam plumes obscure Klyuchevskaya’s summit crater, while black ash covers most of the upper slopes. Emissions from Bezymianny obscure the volcano and much of the surrounding landscape. Both Klyuchevskaya and Kamen (a dormant volcano) stand far higher than Bezymianny, so the peaks extend above Bezymianny’s plume. Snow covers the ground in the region, and long shadows point almost directly north.
