A cluster of lava domes is located in the center of Kussharo caldera, which is partially filled by Lake Kutcharo (upper right). Light-colored areas of hydrothermal alteration cover the slopes of Atosanupuri (left), seen here from the east with the rounded Sawanchisappu lava dome to its right. The far western wall of the 20 x 26 km caldera lies in the clouds at the far end of the lake.
