Go to the official: Pacific Ocean Tsunami Warning Center Founded: 1949Country Operations: National Oceanic and Atmospheric Administration (NOAA) Objective: To predict the future of the Tsunami. To issue a tsunami warning in the Pacific Ocean region a dangerous area when deemed necessary.

The tsunami detection from deep-sea

● National Oceanic and Atmospheric Administration(NOAA) has since 1995 and developed Deep-ocean Assessment and Reporting of Tsunamis(DART) system in 2001, was established six DART stations in the Pacific Ocean.

● This is due to the Sumatra earthquake in 2004, was developed from a heightened awareness of the DART tsunami crisis in the world.

Far from the coast when the tsunami?

Far from shore when the tsunami, the DART station sent to detailed information about tsunami to the PTWC. So there are a number of DART station. Thus, DART was to detect the passage of a tsunami, sending data to the PTWC tsunami. From this system, improved significantly in the Pacific Ocean tsunami warning and tsunami warning.
