The Caribbean Tsunami Warning Program (CTWP)

supports domestic and international the 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 international Tsunami Ready

Programs. 

 

Within NOAA it works closely with the U.S.

Tsunami Warning Centers (National Tsunami Warning

Center and Pacific Tsunami Warning Center), which are

currently providing tsunami services to the

Caribbean; the International Tsunami Information Center;

the NWS San Juan Weather Forecast Office

responsible for disseminating tsunami products to Puerto Rico and the U.S. Virgin Islands; the NOAA Center for Tsunami Research and the National Ocean

Service for water level monitoring. 

 

The CTWP also participates and supports activities of the UNESCO Intergovernmental Oceanographic Commission's 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 CTWP coordinates efforts with the Caribbean Tsunami Information Center (Barbados) and

works closely with the seismic, sea level and GPS operators and the officially designated National Tsunami Warning Focal Points, National Tsunami Warning

Centers and Tsunami National Contacts. The Program organizes and participates in training sessions and provides briefings and materials for use by the general

public, government, scientists and broadcast media. It is staffed by two full time employees and Student Interns. Efforts are made to have resources available in

English, Spanish and French. The CTWP 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 Mayagüez.
