§3203 — Title 33 Navigation and Navigable Waters | U.S. Code

Summary

NOAA, through the National Weather Service, must run a program to detect, forecast, and warn people about tsunamis for the Pacific and Arctic regions and for the Atlantic, including the Caribbean Sea and the Gulf of Mexico. The program must include warning centers, keep at least 80 percent of the Deep-ocean Assessment and Reporting of Tsunamis (DART) buoy array working, use many kinds of detection equipment, keep that equipment in working order, and provide tsunami forecasts and inundation maps using ocean and Earth observing systems, seismic networks, historical data, bathymetry, and new satellite or airborne methods. It must keep good data systems, work with the U.S. Geological Survey and the National Science Foundation for fast seismic information and to support seismic stations installed before April 18, 2017, send warnings quickly to states, territories, and the public using federal systems (including NOAA Weather Radio All Hazards and Wireless Emergency Alerts), allow integration with other observing systems and undersea cables, and use any other technology needed. The program must operate tsunami warning centers, including the National Tsunami Warning Center in Alaska (mainly for Alaska and the continental U.S.) and the Pacific Tsunami Warning Center in Hawaii (mainly for Hawaii, the Caribbean, and other Pacific areas), and add more centers if needed. Those centers must watch seismic, buoy, sea-level, and other data all the time; evaluate earthquakes, landslides, and volcanic events; run models to predict arrival times, flooding, currents, and duration; update inundation estimates; share forecasts and bulletins with governments and the public; coordinate with hazard mitigation, the Coast Guard, and FEMA for port readiness; make data public; keep fail-safe backups; and modernize procedures. NOAA must set uniform operating rules, follow best practices and IT standards, provide needed computing power, make equipment rules, move research into operations, work with other agencies for needed assets, and notify two congressional committees within 30 days of major equipment failures, contractor delays, or a significant tsunami warning, including a short analysis of model accuracy, which detectors worked or failed, and how well warnings reached people.
