The small, 3-km-wide island of Shirinki, part of a chain of volcanoes west of the main Kuril Island arc, is located 15 km west of Fuss Peak on Paramushir Island. Shirinki volcano, also known as Antsiferova, is cut by a 750-m-wide breached summit crater, open to the south. The crater, not visible in this view from the west, contains two lava domes, one of which is very young, possibly historical in age. Photo by Oleg Volynets (Institute of Volcanology, Petropavlovsk).
