The International Tsunami Information Center - Caribbean Office (ITIC-CAR) supports domestic and international tsunami warning services and programs in the Caribbean and adjacent regions. The office focuses on strengthening and sustaining the tsunami observational system as well as the continued enhancement of tsunami outreach, education and readiness, including the implementation of the TsunamiReady® and UNESCO/IOC Tsunami Ready Programme.

The ITIC-CAR also participated and supports activities of the UNESCO Intergovernmental Oceanographic Commission, Intergovernmental Coordination Group for Tsunamis and other Coastal Hazards Warning System for the Caribbean Sea and adjacent regions (CARIBE-EWS). The CARIBE-EWS covers 48 states and territories in the Caribbean and Western Atlantic. The ITIC-CAR coordinates efforts with the Caribbean Tsunami Information Center (CTIC) and  works closely with the seismic, sea level, and GPS operators and the officially designated National Tsunami Warning Forcal Points, National Tsunami Warning Centers and Tsunami National Contacts. The Program organizes and participated in training sessions and provides briefings and materials for use by the general public, government, scientists and broadcast media. It is staffed by one fill time employee and Student Interns. Efforts are made to have resources available in English, Spanish and French. The ITIC-CAR was established in 2010 by the U.S. National Weather Service. It is co-located with the Puerto Rico Seismic Network at the University of Puerto Rico at Mayaguez.
