US NOAA NWS - UNESCO IOC International Tsunami Information Center cover
Mission ITIC supports the IOC through tsunami capacity building and outreach. In the Pacific (PTWS), ITIC continually monitors and recommends improvements to ensure more timely and accurate warnings, assists countries in establishing regional and national tsunami warning systems, acts as a clearinghouse for risk assessment and mitigation activities, and serves as a resource for the development, publication, and distribution of tsunami education and preparedness materials. The US Richard H. Hagemeyer Pacific Tsunami Warning Center (PTWC) serves as the operational tsunami warning headquarters for the PTWS. PTWC works with Japan's Northwest Pacific Tsunami Advisory Center (NWPTAC) and the US West Coast/Tsunami Warning Center (WC/ATWC) to provide international alerts to 46 countries across the Pacific. The system uses more than 400 seismic stations globally to monitor potentially tsunamigenic earthquakes, and more than 1000 channels of sea level data from the Pacific and around the world to verify the generation and severity of a tsunami.

Additionally, since the devastating M9.3 Sumatra earthquake and tsunami in December 2004 that killed nearly 230,000, both the ITIC and PTWC have been involved in supporting the IOC as it coordinates the establishment of a Global Tsunami Warning and Mitigation System that covers the Pacific, Indian, and Atlantic Oceans and the Caribbean and Mediterranean Seas. The ITIC maintains and develops relationships with: intergovernmental organizations, non-governmental organizations, the scientific community, local authorities and the general public.
Description ITIC's Facebook page is an experimental service provided by NWS to explore the use of Facebook to extend the reach of NWS information. Posts here do not always reflect the most current information.

NWS will be using Facebook as a supplemental channel to experimentally disseminate environmental information and promote weather awareness activities including tsunami outreach and educational efforts.
