The Kamchatka Volcanic Arc is a prominent volcanic region located in the Kamchatka Peninsula of eastern Russia. It is part of the larger Pacific Ring of Fire, which is known for its high volcanic activity. The arc consists of over 30 active volcanoes, including notable ones like Klyuchevskaya Sopka and Shiveluch. This volcanic arc is formed by the subduction of the Pacific Plate beneath the North American Plate. The intense geological activity results in frequent eruptions, making it a significant area for studying volcanology and tectonics. The region is also recognized as a UNESCO World Heritage Site due to its unique natural features.
