Goriaschaia Sopka is a young, historically active lava dome at the SW end of Simushir Island in the central Kuriles. The dome is located within a large horseshoe-shaped crater cutting the NW flank of the older Igla Mountain somma volcano. A low saddle separates Igla Mountain from Milne, a large stratovolcano immediately to the SE. Numerous fresh lava flows with prominent marginal levees extend from the Goriaschaia Sopka dome; some reached the sea, where they created an irregular shoreline. The andesitic dome may have formed as recently as the late-19th century. Historical activity, consisting dominantly of mild-to-moderate explosive eruptions, has occurred since 1842.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Two overlapping volcanoes anchor the SW end of Simushir Island, Goriaschaia Sopka and Milne. Goriaschaia Sopka (top) is a young, historically active lava dome that has been the source of youthful lava flows whose margins are visible on the volcano's flanks and form the irregular shoreline at the top of this NASA Space Shuttle image. The dome is located within a large horseshoe-shaped crater cutting the NW flank of the older Igla Mountain volcano. Milne is the large snow-capped stratovolcano immediately to the SE of Goriaschaia Sopka.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
