 Expedition. No other ascents were then recorded until 1931, when several climbers were killed by flying lava on the descent. As similar dangers still exist today, few ascents are made.

Klyuchevskaya Sopka is considered sacred by some indigenous peoples, being viewed by them as the location at which the world was created. Other volcanoes in the region are seen with similar spiritual significance, but Klyuchevskaya Sopka is the most sacred of these. It is said that when the god Volkov created the world, this was the point at which he held it, and so it remains unfinished, unsealed, thus the volcanic activity.

2010 Eruption

As early as 27 February, gas plumes had erupted from Klyuchevskaya Sopka (reaching elevations of 22,500 feet) and during the first week of March 2010, both explosive ash eruptions and effusive lava eruptions occurred until, by 9 March, the ash cloud was reported to have reached an elevation of 20,000 feet. Also, significant thermal anomalies have been reported and gas-steam plumes extended roughly 31 miles to the north-east from the volcano on 3 March.
