About: Outer trench swell

An Entity of Type: place, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The outer trench swell, outer trench high, or outer rise is a subtle ridge on the seafloor near an oceanic trench, where a descending plate begins to flex and fault in preparation for its descent into the mantle at a subduction zone. The lithosphere is bent upwards by plate stresses, and is not in isostatic equilibrium (distinguish from the "outer ridge" of a forearc).

  • The outer trench swell, outer trench high, or outer rise is a subtle ridge on the seafloor near an oceanic trench, where a descending plate begins to flex and fault in preparation for its descent into the mantle at a subduction zone. The lithosphere is bent upwards by plate stresses, and is not in isostatic equilibrium (distinguish from the "outer ridge" of a forearc). (en)
  • 해구 외부 융기대(Outer trench swell) 혹은 간단하게 아웃터라이즈(outer rise), 아우터라이즈는 해구 부근에서 융기한 낮은 높이의 해저 능선으로, 침강하는 해양판이 섭입대에서 맨틀 방향으로 침강하기 위해 습곡과 단층을 형성하기 시작하는 영역이다. 해구 외부 융기대의 암석권은 판의 응력으로 위쪽으로 휘어지기 때문에 지각 평형 상태에 있지 않다. (ko)
  • アウターライズ（英語: outer rise）とは、陸から見て海溝の外側にある海底の隆起地形のこと。 海洋プレートが海溝から沈み込む際に折れ曲がるために形成される。海溝外縁隆起帯。アウターライズ地震断層ではしばしば正断層型の地震が発生する。 (ja)
