NOAA Tsunami Program

Body

The National Oceanic and Atmospheric Administration (NOAA) Tsunami Program is a cross-agency cooperative effort to minimize the impacts of tsunamis. Administered by the National Weather Service (NWS), the program leverages the capabilities of other NOAA operational line offices, including the Office of Oceanic and Atmospheric Research (OAR), the National Ocean Service (NOS), and the National Environmental Satellite, Data, and Information Service (NESDIS).

For more than 50 years, NOAA and its predecessor agencies have had operational responsibility for the U.S. Tsunami Warning System. Today's end-to-end system operates in partnership with federal, state, territorial, international and local organizations, as well as industry. Major components include:

  • Observation systems to rapidly detect tsunami generating earthquakes and tsunamis,
  • Models to forecast tsunami impacts,
  • Timely and accurate messaging,
  • Decision-support services during events to enhance community response, and
  • Preparedness and mitigation activities that enhance response to a tsunami threat and reduce or eliminate potential impacts.
