The dramatic picture of Klyuchevskoy was captured by photographer Marc Szeglat on October 16 at a distance of approximately 9.5 miles from its concealed cone, as the volcano erupted for the first time in three years. The explosion triggered by the eruption could be heard from 20 miles away. In September 1994, an eruption caused disruption after it affected airline routes across the Pacific Ocean. The active nature of the volcano, which first began erupting in 1697, means it is still rarely a target for climbers

Volcanoes can do that, make their own weather phenomena. Sort of makes me wonder which comes first, the electrical surge or the eruption.
