The Kuril-Kamchatka Arc is a volcanic region located in the northwest Pacific Ocean, stretching from the Kuril Islands to the Kamchatka Peninsula in Russia. This area is known for its active volcanoes and frequent seismic activity due to the subduction of the Pacific Plate beneath the North American Plate. The arc consists of numerous islands and volcanic peaks, including notable volcanoes like Klyuchevskaya Sopka and Shiveluch. The region is part of the Ring of Fire, a zone characterized by high volcanic and earthquake activity. It plays a significant role in the study of plate tectonics and volcanic processes.
