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 1902 eruption of Mount Pelée was a volcanic eruption on the island of Martinique in the Lesser Antilles Volcanic Arc of the eastern Caribbean, which was one of the deadliest eruptions in recorded history.
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.
It is the highest mountain peak in the Lesser Antilles, rising 1,467 m (4,813 ft) high. [2] The last magmatic eruption was in 1530±30 during which the current lava dome was emplaced. [3] More recent eruptions have been phreatic in type. [4] On February 8, 1843, an eruption of La Grande Soufrière caused by an earthquake killed over 5,000 ...
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 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.
It is the second highest mountain in the Lesser Antilles, after La Grande Soufrière in Guadeloupe. Morne Diablotin is located in the northern interior of the island, about 24 kilometres (15 mi) north of Dominica's capital Roseau and about 10 kilometres (6.2 mi) southeast of Portsmouth , the island's second-largest town.
Basse-Terre is a volcanic island. [36] 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 ...
