The Klyuchevskaya Sopka ( Russian Ключевская сопка ), also Klyuchevskoi volcano ( Russian Ключевской Вулкан ), on the Kamchatka Peninsula in Russia is the highest active volcano in Eurasia . It is around 8,000 years old and is part of the Pacific Ring of Fire . It is the highest volcano in the densely positioned twelve stratovolcanoes which the Klyuchevskaya group form (after the name of the two main volcanoes as Kljutschewskoi- Bezymianny -Vulkankomplex called). To her belong z. B. also the Kamen and the Ploski Tolbatschik .


Klyuchevskaya Sopka reaches its extraordinary height because it rose from the slope of a large older volcano. On this basis, she piled up an almost perfect cone a good 3,000 meters high. With its total height, the volcano clearly towers above its "competitors" Korjakski (3300 m) and Kronozki (3100 m), which originated in lower elevations. Its top is encompassed by the Erman and Schmidt glaciers. Their shape is conical (conical). The terrain consists of volcanic rubble, interrupted by fields of snow and ice.

Volcanic activity

In 1697, Vladimir Atlasov registered the first recorded eruption during a hike through the Kamchatka.

On average, the volcano erupts every five years, in some periods annually, sometimes continuously over the course of 2 years. The largest eruption in 1944/45 occurred through the main crater .

Further eruptions were observed in 1994 and in the autumn of 2003, with the volcano sending its ash cloud up to a height of 20 kilometers in 1994 .

Since August 2009 the volcano has also shown increased activity again. Smaller secondary craters with an extension of 60 to 200 m at distances of eight to 25 km from the main crater are also active and contribute to the volcanic activity .

Since mid-April 2020, volcanic activity has been evident again. The alert level of the renewed outbreaks was given as "orange".


The volcano is located in the Klyuchevskoy Nature Park , also known as the Kamchatka Volcanoes . 30 km away is the place Klyuchi , from which the name of the volcano comes. The distance to the next larger city Petropavlovsk-Kamchatsky is about 600 km, a common ascent route goes from Kozyrewsk over the saddle between the Klyuchevskaya Sopka and the volcano Kamen . The saddle is at approx. 3300 m. From there you can easily start to climb the summit. At the foot of the volcano, at an altitude of about 1000 m, there are three volcanological stations that are also mountain huts. Deep torrent valleys furrow the landscape at 1000 m. Some hiking trails are marked by piles of stones.

The first ascent took place in 1788 by the mountain guide Daniil Gaus as part of the Billings-Sarytschew expedition (1785-1793).
