Roughly 3.2 million square kilometers (1.2 million square miles) in area, the Caribbean Plate borders the North American Plate, the South American Plate, and the Cocos Plate. These borders are hotspots for seismic activity, including frequent earthquakes and tremors, occasional tsunamis, and volcanic eruptions.  The North American plate, shown in brown The North American Plate is a tectonic plate covering most of North America, extending eastward to the Mid-Atlantic Ridge and westward to the Cherskiy Range in East Siberia. ...

Boundary types

The northern boundary with the North American plate is a transform or strike-slip boundary which runs from the border area of Belize, Guatemala, and Honduras in Central America, eastward through the Cayman trough on south of the southeast coast of Cuba, and just north of Hispaniola, Puerto Rico, and the Virgin Islands. Part of the Puerto Rico Trench, the deepest part of the Atlantic Ocean (roughly 8,400 meters), 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. In plate tectonics, a transform boundary (also known as transform fault boundary, transform plate boundary, transform plate margin, slip boundary or conservative plate boundary) is said to occur when tectonic plates slide and grind against each other along a transform fault. ...

The eastern boundary is a subduction zone, but since the boundary between the North and South American Plates in the Atlantic is as yet undefined, it is unclear which one, or possibly both, is descending under the Caribbean Plate. Subduction forms the volcanic islands of the Lesser Antilles island arc from the Virgin Islands in the north to the islands off the coast of Venezuela in the south. This boundary contains seventeen active volcanoes, most notably Soufriere Hills on Montserrat, Mount Pelée on Martinique, La Grande Soufrière on Guadeloupe, Soufrière Saint Vincent on Saint Vincent, and the submarine volcano Kick-'em-Jenny which lies about 10 km north of Grenada.

Along the geologically complex southern boundary the Caribbean Plate interacts with the South American Plate forming Trinidad (on the South American Plate) and Tobago (on the Caribbean Plate), and islands off the coast of Venezuela (including the Leeward Antilles) and Colombia. This boundary is in part the result of transform faulting along with thrust faulting and some subduction. The rich Venezuelan petroleum fields possibly result from this complex plate interaction.

The western portion of the plate is occupied by Central America. The Cocos Plate in the Pacific Ocean is subducted beneath the Caribbean Plate, just off the western coast of Central America. This subduction forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica.

The Caribbean Plate is thought to be a large igneous province that formed in the Pacific Ocean tens of millions of years ago. As the Atlantic ocean widened, North America and South America were pushed westward, and the Pacific Ocean floor began to subduct under the western edges of the American continents. The Caribbean Plate is thicker and lay higher than the rest of the Pacific Ocean floor, and instead overrode the Atlantic Ocean floor, moving eastward relative to North America and South America, and, with the formation of the Isthmus of Panama 2–3 million years ago, ultimately losing its connection to the Pacific. A large igneous province (LIP) is an extensive region of basalts resulting from flood basalt volcanism. ... The Isthmus of Panama. ...

There is some speculation that the westward motion of the South American Plate may have forced the Caribbean and Scotia Plates at its northern and southern ends respectively to squeeze around it. Both share a similar shape and are being subducted along their eastern boundary.[1] The Scotia plate is shown in blue-green towards the bottom of this map The Scotia Plate is an oceanic tectonic plate bordering the South American Plate on the north, the South Sandwich microplate to the east, and the Antarctic Plate on the south and west. ...

  Results from FactBites:
Convergent, compressional and collisional tectonic activity caused primarily from the eastward movement of the Caribbean Plate in relation to the North American and South American Plates, is responsible for zones of subduction in the region, the formation of island arcs and the evolution of particular volcanic centers on the overlying plate.
Currently, the Caribbean plate is moving eastward in relation to the North and South American Plates at a rate of approximately 20 millimeters per year.
The plate movement is responsible for the zones of subduction along the active boundaries and the formation of the West Indies Volcanic Island Arc on the overlying plate in the eastern region.
Problems with plate tectonics (6123 words)
Plate rigidity is a central tenet of plate tectonics.
Plate velocities are shown by arrows; their length indicates the displacement expected in a period of 25 million years.
Plate tectonicists who recognize the existence of ridge-parallel flow generally argue that a mantle diapir wells up beneath each ocean ridge segment, and that at the crest of each diapir, radial horizontal flow takes place, with a significant component parallel to the strike of the ridge and in opposite directions.
