The Puerto Rico–Virgin Islands microplate (PRVI), also known as the Puerto Rico–Virgin Islands block, is a tectonic microplate formed at the boundary zone between the Caribbean plate and the obliquely subducting North American plate.
During the Carboniferous period, Puerto Rico was submerged. [2] Puerto Rico lies at the boundary between the Caribbean Plate and North American Plate. This means that it is currently being deformed by the tectonic stresses caused by the interaction of these plates. These stresses may cause earthquakes and tsunamis.
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]
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 archipelagos of Puerto Rico and the Virgin Islands except for Saint Croix also lie on the same tectonic plate, the Puerto Rico–Virgin Islands microplate. Satellite image of Puerto Rico, 2008 Around 60% mountainous, the main island of Puerto Rico has one principal mountain range covering the central region of the island from west to east ...
The Puerto Rico Trench is located at a boundary between two plates that pass each other along a transform boundary with only a small component of subduction. The Caribbean plate is moving to the east relative to the North American plate .

Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
