NOAA's two Tsunami Warning Centers (US National Tsunami Warning Center and Pacific Tsunami Warning Center) have separate Areas of Responsibility or Service. The Area of Service is the geographical area within which each Center has the responsibility for the dissemination of messages and the provision of tsunami threat information.

In the United States, the Warning Centers provide warning bulletins to State and Local Emergency Managers and other officials. Internationally, bulletins are provided as advice to the country's National Tsunami Warning Center, through their Tsunami Warning Focal Point, to assist in their decision-making for issuing warnings to their populations.

All NOAA tsunami bulletins are also made available to the news media and the public.
