The '''Kuril–Kamchatka Trench''' or '''Kuril Trench''' ({{langx|ru|Курило-Камчатский жёлоб}}, ''Kurilo-Kamchatskii Zhyolob'') is an [[oceanic trench]] in the northwest [[Pacific Ocean]]. It lies off the southeast coast of [[Kamchatka]] and parallels the [[Kuril Islands|Kuril Island]] chain to meet the [[Japan Trench]] east of [[Hokkaido]]. It extends from a [[triple junction]] with the [[Ulakhan Fault]] and the [[Aleutian Trench]] near the [[Commander Islands]], Russia, in the northeast, to the intersection with the Japan Trench in the southwest.
The '''Kuril–Kamchatka Trench''' or '''Kuril Trench''' ({{langx|ru|Курило-Камчатский жёлоб}}, ''Kurilo-Kamchatskii Zhyolob''), also known in Japan as {{Nihongo|'''Chishima Trench'''|千島海溝|Chishima Kaikō|lead=yes}}, is an [[oceanic trench]] in the northwest [[Pacific Ocean]]. It lies off the southeast coast of [[Kamchatka]] and parallels the [[Kuril Islands|Kuril Island]] chain to meet the [[Japan Trench]] east of [[Hokkaido]]. It extends from a [[triple junction]] with the [[Ulakhan Fault]] and the [[Aleutian Trench]] near the [[Commander Islands]], Russia, in the northeast, to the intersection with the Japan Trench in the southwest.


The trench formed as a result of the [[subduction]] zone, which formed in the late [[Cretaceous]], that created the Kuril [[island arc]] as well as the Kamchatka volcanic arc. The [[Pacific plate]] is being subducted beneath the [[Okhotsk plate]] along the trench, resulting in intense [[volcanism]].
