- Japan Trench
The Japan Trench is an
oceanic trench, a part of the Pacific Ring of Fire, in the floor of the northern Pacific Oceanoff northeast Japan. It extends from the Kuril Islandsto the Bonin Islandsand is 9,000 m (30,000 ft) at its deepest. It is an extension of the Kuril-Kamchatka Trenchto the north and the Izu-Ogasawara Trenchto its south. This trench is created when the oceanic Pacific plate subducts beneath the continental Eurasian plate. The subduction process, together with the friction created 'drags' the plates downwards, causing a deep-sea trench to be formed. The Japan Trench is one of the causes of the tsunamisand earthquakesin Japan.
August 11 1989the Shinkai 6500 three-person submersible descended to 6,526 m (21,414 ft.) while exploring the Japan Trench.
In October 2008, a UK-Japan team discovered a shoal of fish, "
Pseudoliparis amblystomopsis" at a depth of 7.7km (4.8 miles) in the trench, these are believed to be the deepest living fish ever recorded.
