Detection Technology
The DART(Deep-ocean Assessment and Reporting of Tsunamis).This system is made up of a series of buoys around the Pacific Ocean and parts of the Atlantic Ocean. When a buoy detects a sudden rise in sea level, which may indicate a tsunami, it sends information about sea motion in the area it is in a tsunami warning centre. After confirming that a tsunami has formed, the centre issues evacuation alarms to the endangered coastlines.
