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 .
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 ...
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 ...

The highest elevation point in Puerto Rico, Cerro de Punta (4,390 feet or 1,338 meters), [23] is located in the Cordillera Central, while El Yunque, one of the most popular peaks in Puerto Rico, located in the Sierra de Luquillo and part of El Yunque National Forest, has a maximum elevation of 3,540 feet (1,080 m).
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.
Felt throughout Puerto Rico, the Dominican Republic, and the US and British Islands. It is colloquially known as the 2010 Moca earthquake. It caused minor damage in the western and northwestern regions of Puerto Rico, and a minor landslide that affected a portion of PR-111. It is the largest Puerto Rican earthquake to have occurred on land in ...
The deepest point of the South Sandwich Trench is only 110 metres (361 ft) shallower than the deepest point in the Puerto Rico Trench, sometimes known as the Milwaukee or Brownson Deep. The trench is produced by the subduction of the southernmost portion of the South American plate beneath the small South Sandwich plate .
