WebA 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. WebOnce a tsunami has been generated, its energy is distributed throughout the water column, regardless of the ocean's depth. A tsunami is made up of a series of very long waves. The waves will travel outward on the surface of the ocean in all directions away from the source area, much like the ripples caused by throwing a rock into a pond. simplicity\\u0027s fo
