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 is at a complex transition from the subduction boundary to the south and the transform boundary to the west. 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.
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 .
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 ...
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 ...
The warning was issued Saturday evening for the U.S. territories of Puerto Rico and the Virgin Islands after a magnitude 7.6 earthquake occurred at a depth of 10 km in the Caribbean Sea around 6: ...
Geologically separated from the Greater Antilles island of Hispaniola by the Mona Passage and from the Lesser Antilles island arc by the Anegada Passage, the main island of Puerto Rico, the Spanish Virgin Islands of Vieques and Culebra, the British Virgin Islands, and the U.S. Virgin Islands except for the southernmost island of Saint Croix all lie on the same carbonate platform and insular ...
