Tsunamis are long waves formed from a sudden displacement of the sea floor due to a fault rupture, landslide, or volcanic activity. Given that Puerto Rico lies above a subduction zone in the Caribbean Sea, it is especially susceptible to large earthquakes and tsunamis. The greatest tsunami ever recorded in Puerto Rico occurred from an earthquake off the Mona Passage in 1918. The USGS Earthquake Hazards Program and the USGS Coastal and Marine Hazards and Resources Program are studying the risks of tsunamis in Puerto Rico and have developed detailed maps of the Caribbean fault traces. On this page, explore all tsunami hazard publications, data releases, and news for Puerto Rico.
Los maremotos son olas largas formadas por un desplazamiento repentino del suelo marino debido a la ruptura de una falla, un deslizamiento de tierra o actividad volcánica. Dado que Puerto Rico reside sobre una zona de subducción en el Mar Caribe, es especialmente susceptible a terremotos y maremotos. El maremoto más grande que se registró en Puerto Rico se produjo debido a un terremoto en el Canal de la Mona en 1918. El Programa sobre los Peligros de los Terremotos del USGS y el Programa de Recursos y Peligros Costeros y Marinos del USGS estudian los riesgos de los maremotos en Puerto Rico y desarrolló mapas detallados de la localización de las fallas del Caribe.

Mysterious tsunami in the Caribbean Sea following the 2010 Haiti earthquake possibly generated by dynamically triggered early aftershocks
Dynamically triggered offshore aftershocks, caused by passing seismic waves from main shocks located on land, are currently not considered in tsunami warnings.

The Puerto Rico trench exhibits great water depth, extremely low gravity anomaly, and a tilted carbonate platform between (reconstructed) elevations of +1300 m and -4000 m. we suggest that these features are manifestations of large vertical movements of a segment of the Puerto Rico Trench, its forearc, and the island of Puerto Rico that took place 3.3 m.y. ago over a time period as short as 14-40...Caribbean Tsunami and Earthquake Hazards Studies-Tsunami Potential
Newly-acquired multibeam bathymetry of the entire Puerto Rico trench reveals numerous retrograde slope failures at various scales at the edge of the carbonate platform north of Puerto Rico and the Virgin Islands.

Strike-slip faults in the forearc region of a subduction zone often present significant seismic hazard because of their proximity to population centers.
