The National Oceanic and Atmospheric Administration (NOAA) has a system of six buoys that are called the Deep-Ocean Assesment and Reporting of Tsunami, or DART. Three are located along the Aleutian Islands of Alaska, 2 are off the Washington/Oregon coasts, and 1 along the Equator.
By mid 2007 NOOA will deploy 32 new DART buoys to monitor activity throughout the entire Pacific, Atlantic and Caribbean.
