Rucharu, with the small cones of Golets and Tornyi, is SW of Moyorodake (Medvezhia) volcano at one of the narrowest parts of Iturup Island, and formed during the late Pleistocene or early Holocene. A small lava flow from the Tornyi cone reportedly occupies a broad glacial cirque. The andesitic-dacitic Golets cone, constructed above the eroded remnants of the Pleistocene Parusnaya Mountain volcano, produced lava flows that reached the coast. Those features are on the NE side of the Vetrovoi Isthmus (or Ruchuru) Caldera, a 6-7 km wide feature formed during a Pleistocene submarine eruption; a 1-km-wide explosion crater with a small cone (Klumba) is on its western margin (Gorshkov 1970).
