Location map Puerto Rico Trench—United States Geological Survey Perspective view of the sea floor of the Atlantic Ocean and the Caribbean Sea. The Lesser Antilles are on the lower left side of the view and Florida is on the upper right. The purple sea floor at the center of the view is the Puerto Rico Trench, the deepest part of the Atlantic ...
Milwaukee Deep, also known as the Milwaukee Depth, is the deepest part of the Puerto Rico Trench, constituting the deepest points in the Atlantic Ocean. [1] Together with the surrounding seabed area, known as Brownson Deep, the Milwaukee Deep forms an elongated depression that constitutes the floor of the trench. As there is no geomorphological ...
Puerto Rico Puerto Rico Trench *8.0–8.5 IX – – Possibly the strongest earthquake to have hit Puerto Rico since the European colonization. It was strongly felt throughout the island and major damage was reported everywhere except for in the south (although there were minor damage in colonial buildings in Ponce).
Bathymetry of the northeast corner of the Caribbean Plate showing the major faults and plate boundaries; view looking south-west. The main bathymetric features of this area include: the Lesser Antilles volcanic arc; the old inactive volcanic arc of the Greater Antilles (Virgin Islands, Puerto Rico, and Hispaniola); the Muertos Trough; and the Puerto Rico Trench formed at the plate boundary ...
Consisting of the archipelagos of Puerto Rico and the Virgin Islands, it is bounded to the north by the Puerto Rico Trench, to the south by the Muertos Trough, to the east by the Virgin Island Basin, Anegada Gap, and Sombrero Basin in the Anegada Passage, and to west by the Yuma Basin and Mona Canyon in the Mona Passage.
From there it continues into Puerto Rico, and the Virgin Islands. Part of the Puerto Rico Trench, the deepest part of the Atlantic Ocean (roughly 8,400 metres or 27,600 feet), lies along this border. The Puerto Rico Trench is at a complex transition from the subduction boundary to the south and the transform boundary to the west.
The Geology of Puerto Rico can be divided into three major geologic provinces: The Cordillera Central, the Carbonate, and the Coastal Lowlands. [1] Puerto Rico is composed of Jurassic to Eocene volcanic and plutonic rocks, which are overlain by younger Oligocene to recent carbonates and other sedimentary rocks .
The Puerto Rico Trench, the largest and deepest trench in the Atlantic, is located about 71 mi (114 km) north of Puerto Rico at the boundary between the Caribbean and North American plates. [93] It is 170 mi (270 km) long. [94] At its deepest point, named the Milwaukee Deep, it is almost 27,600 ft (8,400 m) deep. [93]
