Goriaschaia Sopka volcanGoriaschaia Sopka (also spelled Goriaschaya Sopka) is a frequently active volcano on SW Simushir Island, Kurile Islands.
Its active vent is an andesitic lava dome volcano within a large horseshoe-shaped crater cutting the NW flank of what is left of the older Igla Mountain volcano (a somma). Igla Mountain is very close to Milne volcano.
The Sopka dome is probably only about 150 years old. It has erupted many young lava flows with prominent marginal levees. Some of them reached the sea where they created an irregular shoreline.
Observed historical activity were mainly mild to moderate ash explosions and strombolian.
