Intergovernmental Oceanographic Commission (IOC) Tsunami Programme
The United Nations Educational, Scientific and Cultural Organization's IOC Tsunami Programme aims to reduce the loss of lives and livelihoods from tsunamis worldwide. To do this, it supports IOC member states in assessing tsunami risk, implementing tsunami early warning systems, and educating at-risk communities about preparedness. Four Intergovernmental Coordination Groups (ICG) corresponding to the regions Pacific, Caribbean, Indian Ocean, and Mediterranean have been established to address particular regional needs.
International Tsunami Information Center (ITIC)
The National Weather Service's ITIC supports the IOC's Tsunami Program as well as its Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System (PTWS). The ITIC's responsibilities include monitoring PTWS activities, coordinating tsunami warning system technology transfer among PTWS member states, acting as a clearinghouse for risk assessment and mitigation activities, and producing tsunami education and preparedness materials. The ITIC also works closely with the World Data System for Geophysics on international data stewardship, product development, and outreach.
Caribbean Tsunami Warning Program (CTWP)
The National Weather Service's CTWP supports improved tsunami observations, provides training and outreach and education assistance, and facilitates data exchange for domestic and international partners in the Caribbean and adjacent regions. CTWP is part of the IOC's Intergovernmental Coordination Group for Tsunamis and Other Coastal Hazards Warning System for the Caribbean Sea and Adjacent Regions.
