Ring of Fire the east and the Okhotsk Sea to the west. Immediately offshore along the Pacific coast of the peninsula runs the 10,500-m-deep Kuril-Kamchatka Trench, where rapid subduction of the Pacific Plate fuels the intense volcanism. Almost all types of volcanic activity are present, from stratovolcanoes and shield volcanoes to Hawaiian-style fissure eruptions. Over 30 active volcanoes and hundreds of dormant and extinct volcanoes are in two major volcanic belts. The most recent activity takes place in the eastern belt, starting in the north at the Shiveluch volcanic complex, which lies at the junction of the Aleutian and Kamchatka volcanic arcs. Just
Circum-Superior Belt pounds of nickel. At least two nickel deposits are in progress by Vale Inco at the Thompson and Birchtree mines. At least 70 million pounds of nickel has been mined since 2005. At the city of Thompson, nickel of the Thompson Belt is smelted and refined in facilities. This smelting and refining process contributes to about one-third of the total nickel output in Canada. In the Cape Smith Belt of northern Quebec, the Raglan Mine lies in copper-nickel deposits of the ultramafic Katiniq Suite sills. The Katiniq Suite sills are also within an area that is presently explored for nickel,
