Ilyinsky Volcano

Ilyinsky Volcano. Ilyinsky Volcano is one of the most beautiful volcanoes on Kuril Lake with its perfectly-formed cone. With a height of 1,578 meters and a diameter at its base of eight kilometers, this is one of the youngest active volcanoes on Kamchatka. This volcano is the most noticeable adornment in the lake’s panorama on calm, sunny days. Ravines are practically absent from its inverted slopes, which are covered with pumice stone. A hot beach with thermal springs lies in the place where the volcano’s slope touches Kuril Lake’s waters, in Tyoplaya (Warm) Bay. The only known eruption was in 1901, when four crater funnels were formed, the largest of which is 800 by 1,200 meters with a depth of over 400 meters.
