Plosky Tolbachik Volcano
Plosky Tolbachik belongs to Klyuchevskoy Volcanic group on the eastern range. It is on the territory of of Klyuchevskoy Volcano Nature Park included in the UNESCO World Cultural and Natural Heritage List.
It is a 3,682 meters high shield-volcano with a 1,800 meters wide and 450 meters deep caldera on its summit. This caldera is the result of the great fissure eruption of the volcano that took place from July 6, 1975 to December 10, 1976.
This eruption deeply and permanently modified the surroundings of the volcano. It created two breaks: the northern and southern breaks. 4 scoria cones were also born, while on an area of 400 sq-km all vegetation was destroyed. The former lava shield was covered with a thick layer of cinder (or scoria) and ashes, and a thin pyroclastic flow spread all the way to a thousand kilometers.
Ascending Plosky Tolbachik volcano and the cones and taking a walk in the “Dead Forest” give you an idea of the scale of this phenomenal eruption that shattered the peninsula for more than a year.
