Central America and the Caribbean Plate.Physiographically, Central America is the tapering isthmus of southern North America, extending from the Isthmus of Tehuantepec in southern Mexico southeastward to the Isthmus of Panama where it connects to the Colombian Pacific Lowlands in northwestern South America. Alternatively, the Trans-Mexican Volcanic Belt delimits the region on the north. Central America has an area of some 592,000 square kilometres. The Pacific Ocean lies to the southwest, the Caribbean Sea lies to the northeast, and the Gulf of Mexico lies to the north. Most of Central America rests atop the Caribbean Plate.
