Administered by the National Oceanic and Atmospheric Administration, and based in Hawaii and Alaska, the Pacific Tsunami Warning Center is the command center for monitoring and warning all nations which may be affected by a tsunami. With data from a network of 39 detection buoys called the Deep-Ocean Assessment and Reporting of Tsunami array, the center can issue alerts of real time earthquake activity in the Pacific basin, and the tsunamis that may result, giving residents affected time to head to safe ground, away from low lying coastal areas.
