Klyuchevskaya Sopka is a stratovolcano in Russia. It is the tallest mountain in the country’s Kamchatka Peninsula. You may also have heard it being called Klyuchevskaya Volcano.

Why Is It Famous?

The fame of Klyuchevskaya Sopka is due to its status as the highest mountain within Siberia and being the highest Eurasian active volcano. Additionally, some indigenous people consider Klyuchevskaya Sopka to be sacred, as this is considered the spot where the world’s creation occurred.

What Is Nearby?

The Bering Sea is about 100 kilometers from the volcano. The volcano is in the Volcanoes of Kamchatka UNESCO World Heritage Site.

Geological Description

Klyuchevskaya Sopka features symmetrical cone towers that are steep. The volcano has erupted consistently, with at least 50 eruptions since 1700. At almost any given moment, there will be smoke billowing over the summit.

The volcano features a truncated cone that has a central crater. There is also 70 lateral craters plus cones along the lower slopes. The most recent eruptive period began January 2, 2015, following a year of inactivity. This led to a strombolian eruption ending January 16, with further minor eruptions between March 10 and 24.  

Events In Time

The volcano appeared about 6,000 years ago, with its first eruption on record occurring in 1697. Since then, it has been active continuously, as the volcanoes nearby have as well. The first successful climb of the volcano was in 1788. However, the ascent ended poorly with several climbers dying from flying lava while descending. Afterward, there were no other ascents on record until 1931.

Few people attempt to climb it in recent history due to the prevalence of eruptions. Recent eruptions occurred in 2007, 2010, 2012, 2013, and 2015. The Kamchatka Volcanological Station was established in 1935 at the base of the volcano.
