Klyuchevskoy has produced many small to moderate-volume explosive and effusive eruptions without major periods of inactivity. More than 100 flank eruptions have occurred during the past roughly 3,000 years, with most craters and cones occurring on the NE (seen here) and SE flanks, at elevations of 500-3,600 m.
