Some of the world’s most active volcanoes make up the spine of the Kamchatka Peninsula in far east Russia. Kamchatka is the northwestern edge of the Pacific “ring of fire,” where earthquakes and volcanism are caused by ongoing subduction of the Pacific oceanic plate beneath the Eurasian plate. This astronaut photograph profiles the summit area of Ksudach Volcano, also called Voniuchi Khrebet Volcano, in southern Kamchatka. White snow on the ridges in this image contrasts with the dark volcanic soils and highlights the well-developed radial drainage pattern down the slopes of the volcano.
