Title 33 › CHAPTER 45 — TSUNAMI WARNING AND EDUCATION › § 3206

Last updated Sep 22, 2026|Official source

Summary

The Administrator must help build a worldwide tsunami forecast and warning system by giving technical help, operational support, and training to international groups like the Intergovernmental Oceanographic Commission and the World Meteorological Organization, and to other appropriate partners. The National Weather Service can run an International Tsunami Information Center to help Pacific nations (and other nations in the global system) by tracking warning activities, helping countries set up national warning systems and share current technologies, keeping a library of tsunami materials, and sharing educational and research information. The National Weather Service must focus first on helping countries find vulnerable coasts, make flood maps, get or design real‑time detection and reporting gear, and build communication and warning networks. It can help transfer detection and communications technology and provide technical support for international tsunami programs. When deciding to help, it may consider a country’s data‑sharing practices and should encourage full, open data exchange.

(a)Support for development of an international tsunami warning system
The Administrator shall, in coordination with the Secretary of State and in consultation with such other agencies as the Administrator considers relevant, provide technical assistance, operational support, and training to the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific, and Cultural Organization, the World Meteorological Organization of the United Nations, and such other international entities as the Administrator considers appropriate, as part of the international efforts to develop a fully functional global tsunami forecast and warning system comprised of regional tsunami warning networks.
(b)International Tsunami Information Center
The Administrator, through the National Weather Service and in consultation with other relevant Administration offices, in cooperation with the Intergovernmental Oceanographic Commission, may operate an International Tsunami Information Center to improve tsunami preparedness for all Pacific Ocean nations participating in the International Tsunami Warning System of the Pacific, and may also provide such assistance to other nations participating in a global tsunami warning system established through the Intergovernmental Oceanographic Commission. As part of its responsibilities around the world, the Center may—
(1)monitor international tsunami warning activities around the world;
(2)assist member states in establishing national warning systems, and make information available on current technologies for tsunami warning systems;
(3)maintain a library of materials to promulgate knowledge about tsunami in general and for use by the scientific community; and
(4)disseminate information, including educational materials and research reports.
(c)Detection equipment; technical advice and training
In carrying out this section, the National Weather Service—
(1)shall give priority to assisting nations in identifying vulnerable coastal areas, creating inundation maps, obtaining or designing real-time detection and reporting equipment, and supporting communication and warning networks and contact points in each vulnerable nation;
(2)may support a process for transfer of detection and communication technology to affected nations for the purposes of supporting the international tsunami warning system; and
(3)shall provide technical and other assistance to support international tsunami programs.
(d)Data-sharing requirement
The National Weather Service, when deciding to provide assistance under this section, may take into consideration the data sharing policies and practices of nations proposed to receive such assistance, with a goal to encourage all nations to support full and open exchange of data.
