The Golovnin caldera is located at the south of Kunashir Island, the southernmost island of the Kuril chain.
The last Golovnin caldera-forming eruptions occurred ~ 40 ka ago. The caldera is about 6 km in diameter, with an area of 27 km2 and the caldera floor at circa 130 m a.s.l. The caldera rim, 400–500 m a.s.l., is cut by a canyon of the Ozernaya River. Four extrusive domes within and one outside the caldera extend along a line in the SE-NW direction. The Kipyaschee (Boiling) Lake with an area of 0.045 km2 is drained by the 400 m-long Sernyi (Sulphur) Creek to the Goryachee Lake that has an area of circa 3 km2. The latter is drained by the 3 km-long Ozernaya Stream to the Sea of Okhotsk. Both lakes are fed by hot fluids from the lake bottoms and from thermal fields on the lake shores. There are several thermal fields inside the caldera at shores around of the Goryachee Lake with steam vents, boiling pools, mud pools and low-discharge hot bubbling springs: Bezymyannoe (Nameless) Field, Cherepakhovoe (Turtle) Field and Central West Field (CW). Besides, many bubbling spots can be seen on the lake surface. The Kipyaschee Lake is a young (circa 1 ka) maar formed by hydrothermal eruption. There are also several hot springs and steam vents on the shore of the Kipyaschee Lake, as well as numerous vents on the lake floor. This thermal area is named the Central Eastern Field (CE).
Outside the caldera, several groups of thermal springs named the Alyokhinskie springs stretch for circa 2 km along the coast line of the Sea of Okhotsk.
