Protect People From Tsunami Hazard
Tsunami is a naturally occurring series of waves that can result when there is a rapid, large-scale disturbance of a body of water. The most common triggering events are earthquakes below or near the ocean floor, but a tsunami can also be created by volcanic activity, landslides, undersea slumps, and impacts of extra-terrestrial objects. The waves created by this disturbance propagate away from the source. Upon reaching the shoreline the waves can have hazardous, height and force, penetrating inland, damaging structures, and flooding normally dry areas. Also, this wave can cause very severe currents. These currents can turn out to be an earthquake, typhoon, avalanche, fire or flood. The tsunami in Japan caused nuclear accidents, in the Fukushima Daiichi Nuclear Power Plant complex, and the associated evacuation zones affecting hundreds of thousands of residents. Residents within a 20 km radius of the Fukushima Daiichi Nuclear Power Plant and a 10 km radius of the Fukushima Daini Nuclear Power Plant were evacuated. In addition, the U.S. recommended that its citizens evacuate everyone within up to 80 km of the plant.
