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 ...
At this trench the North American Plate is being subducted by the Caribbean Plate. This subduction zone is responsible for the volcanism of the West Indies to the southeast of Puerto Rico. A major transform fault extends from the Puerto Rico trench along the northern coast of Puerto Rico and on through the Cayman Trough to the coast of Central ...
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).
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. [94] It is 170 mi (270 km) long. [95] At its deepest point, named the Milwaukee Deep, it is almost 27,600 ft (8,400 m) deep. [94]
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 ...

Desecheo Island sits on the Desecheo ridge, a narrow east-west ridge that extends west from the northwest corner of Puerto Rico. The ridge forms the southern boundary of the 4-kilometer-deep (2.5 mi) Mona Canyon, which extends toward the north into the Puerto Rico Trench. The east face of the rift has a sharp relief of 3 kilometers (1.9 mi) and ...
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.
