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 .

The Virgin Islands and Puerto Rico do not have active volcanic activity since approximately 30 million years ago, [18] while the last active volcanoes in Hispaniola, Thomazanue and Morne la Vigie, became extinct within 1.5 million years ago. However, the islands are at risk of earthquakes and tsunamis. The Puerto Rico Trench has produced ...
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 ...

CLIP formed as a large igneous province and now forms a thickened zone of oceanic crust between the North American and South American plates. [2] In some places the oceanic crust is 2–3 times as thick as normal oceanic crust (15–20 km (9.3–12.4 mi) vs 7 km (4.3 mi).
