A DART system combines a surface buoy and a sensor on the ocean floor. This sensor detects changes in water pressure and seismic activity and transmits the data back to the surface. If these changes indicate a tsunami may form, the buoy signals an alert via satellite to the Tsunami Warning Centers in Alaska and Hawaii.
