DART stations consist of a bottom pressure sensor anchored to the seafloor and a companion moored surface buoy. An acoustic link transmits data from the bottom pressure sensor to the surface buoy, and then satellite links relay the data to NOAA tsunami warning centers. The DART network serves as the cornerstone to the U.S. tsunami warning system.
Other components of the tsunami warning system include NOAA's tsunami warning centers, a network of tide and seismic stations, forecast models for at-risk communities, and TsunamiReady�, a public preparedness and education program.
Since the Indonesian tsunami of December 2004, NOAA has made significant upgrades to the U.S. tsunami warning system, including:
- Installing 49 new or upgraded tide gages
- Installing or upgrading eight seismic stations
- Expanding the network of DART buoys from six (exclusively in the eastern Pacific) to 39 (from the western Pacific to the Atlantic)
- Growing the number of TsunamiReady communities from 16 to more than 50 today
- Developing 26 inundation forecast models and implementing a new Tsunami Warning System
- Extending the operations of the Pacific and West Coast/Alaska Tsunami Warning Centers to 24 hours a day
- Assisting Australia and Indonesia with installing tsunami warning systems off their coasts.
NOAA encourages state and local communities to improve their resiliency to tsunamis by participating in the TsunamiReady program. This program serves to educate the public about the threat of a tsunami and ensure people know what to do when NOAA issues a tsunami warning. Through active research, NOAA is working to detect tsunamis and issue warnings more rapidly. These efforts will enhance NOAA's ability to protect the American people from the potentially devastating hazard of a U.S.-bound tsunami.
The National Oceanic and Atmospheric Administration, an agency of the U.S. Commerce Department, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of our nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 70 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
