As tsunami waves move across the ocean and pass over a DART, the paired surface buoy reports actual tsunami measurements from the ocean bottom to the Centers. Coastal tide gauge stations and thirty-nine (39) deep-ocean stations are maintained in waters where earthquakes are likely to cause tsunamis. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins. NOAAs National Weather Service serves as Program administrator and supports the worldwide network of DART systems, seismic station networks, and coastal and flooding detectors, activities to improve forecasts, data management, international hazard assessment, and the National Tsunami Hazard Mitigation Program. Google Maps interface to recent and historical tsunamis When this happens underwater, big gaps may appear on the ocean floor. A tsunami only becomes hazardous when it approaches land. Sometimes, before a tsunami hits, there is a huge vacuum effect, sucking water from harbours and beaches. People can see the ocean floor littered with flopping fish and other sea animals. Tsunami warning capabilities have become dramatically better since the 2004 Indian Ocean tsunami. The wavelength decreases, the height increases, and currents intensify. Thanks to a local citizens photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documentedmeteotsunamiin the Great Lakes caused by an atmospheric inertia-gravity wave.
