A crater on the Tomariyama caldera floor contains fumarolic areas with sulfur deposition along the lake shore and beneath the lake. It is the southernmost volcano in the Kuril Islands and forms the southern end of Kunashir Island across the Nemuro Strait from Hokkaido. It contains a 4-5 km wide caldera with several lava domes on its floor. Photo by Yuri Doubik (Institute of Volcanology, Petropavlovsk).
