The Introduction of Tsunami Tsunamis are destructive waves caused by earthquakes， volcanic eruptions， underwater landslides， or climate change. The speed of tsunamis can be as high as 100m/s to 200m/s in the ocean. And it can cross the ocean within hours. The wavelength can reach hundreds of kilometers and the tsunami can spread thousands of kilometers with little energy loss. The waves are less than a meter high in the ocean， but when they reach the coast， their wavelength is shortened and the wave height increases dramatically， reaching tens of meters， forming a "water wall" with enormous energy.SKj红软基地
