Raususan contains two nested calderas, the larger is 6-7 km in diameter and the smaller is 3-3.5 km in diameter. A cone that formed inside the younger caldera is seen here from the E, near the settlement of Yuzhno-Kurilsk. A phreatic explosion was recorded in 1880. The Goryachy Plyazh geothermal field is located outside the caldera along the Pacific coast. Photo by Oleg Volynets (Institute of Volcanology, Petropavlovsk).
