The Lesser Antilles subduction zone is a convergent plate boundary on the seafloor along the eastern margin of the Lesser Antilles Volcanic Arc. In this subduction zone, oceanic crust of the South American plate is being subducted under the Caribbean plate .
The Lesser Antilles more or less coincide with the outer cliff of the Caribbean Plate. Many of the islands were formed as a result of the subduction of oceanic crust of the Atlantic Plate under the Caribbean Plate in the Lesser Antilles subduction zone. This process is ongoing and is responsible not only for many of the islands, but also for ...
The Lesser Antilles Volcanic Arc is a volcanic arc that forms the eastern boundary of the Caribbean Plate. It is part of a subduction zone , also known as the Lesser Antilles subduction zone , where the oceanic crust of the North American Plate is being subducted under the Caribbean Plate. [ 2 ]
The eastern boundary is a subduction zone, the Lesser Antilles subduction zone, where oceanic crust of the South American plate is being subducted under the Caribbean plate. Subduction forms the volcanic islands of the Lesser Antilles Volcanic Arc from the Virgin Islands in the north to the islands off the coast of Venezuela in the south.
Mount Pelée is the result of a typical subduction zone.The subduction formed the Lesser Antilles island arc, a curved chain of volcanoes approximately 850 kilometres (530 mi) in length, between Puerto Rico and Venezuela, where the Caribbean Plate meets Atlantic oceanic crust belonging to the South American Plate.
The Lesser Antilles are at the outer edge of the Caribbean Plate, and Guadeloupe is part of the outer arc of the Lesser Antilles Volcanic Arc. Many of the islands were formed as a result of the subduction of oceanic crust of the Atlantic Plate under the Caribbean Plate in the Lesser Antilles subduction zone. This process is ongoing and is ...
The U.S.Virgin Islands are part of the Greater Antilles that lies parallel to the Puerto Rico Trench; an oblique subduction zone where the North American plate is underthrusted beneath the Caribbean plate along the Lesser Antilles subduction zone transits to strike-slip along the Septentrional-Oriente fault zone.
The trench is associated with a complex transition from the Lesser Antilles frontal subduction zone between the South American plate and Caribbean plate to the oblique subduction zone and the strike-slip transform fault zone between the North American plate and Caribbean plate, which extends from the Puerto Rico Trench at the Puerto Rico ...
