Zavaritzki volcano contains three nested calderas that are 10, 8, and 3 km in diameter. The walls of the youngest caldera are seen here in an aerial view taken before a 1957 eruption that formed a new lava dome and decreased the size of the caldera lake. A scoria cone (top center in this view with N to the right) forms a peninsula on the N side of the caldera. The small lava dome in the center of the crater and the small lava dome island to the lower right were emplaced sometime between 1916 and 1931. Photo courtesy of G.S. Gorshkov, Institute of Volcanology, Petropavlovsk (published in Green and Short, 1971).
