Atosanupuri lava dome was emplaced about 1,000 years ago and its hydrothermally altered flanks are visible in this photo. The 900-m-wide dome was constructed within a 1-km-wide crater. Atosanupuri is one of a cluster of lava domes that occupy the eastern side of Kussharo Caldera. Photo by Lee Siebert, 1977 (Smithsonian Institution).
