The Kamchatka Peninsula is a 1,250-kilometre-long peninsula in the Russian Far East, with an area of about 270,000 km2. The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the 9,600-metre-deep Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and Karaginsky Island constitute Kamchatka Krai of the Russian Federation.
