6.A tsunami wave of water caused by the movement of ocean water volume is large rocks or a large earthquake. The eruption of a volcano and other underwater blasting Landslide and to skid glaciers falling meteors and other distractions. Whether above or under the plain water may cause a tsunami either end of tsunami waves is much different from ordinary water. The waves can travel into the far distance. And destroy the coast away from the origin, thousands of kilometers away. Generally, a tsunami, a wave in the water will travel more slowly than the earthquake's seismic waves, as travel in the ground. Therefore, The waves are generally essential properties measured on two reasons in the mouth, which is the time between the wave two balls and the wavelength is the distance between two wave ball. In the open sea, there are tsunami lessons long. At the same time it has a very long wave length by several hundred kilometers long. While the General wave that is caused by the wind, the coast with about 10 seconds and is about 150 metres wavelength only. Tsunami will move with the speed ranging from 500 to 1,0 kilometres per hour. However, When access to the shore with depths reduced. Wave will have a lower speed and high-wave formation is initiated by more than 30 meters in height may be
.Tsunami will move from the origin, so the coast is sheltered by the rest of the land, usually from wave, however, is still a chance that the wave will be able to turn Ben into impact. In addition The strength depends on the origin and nature of the terrain it
.The wave is a behaviour "shallow water waves," he said. When the ratio between the water depth and the size of the wave, it is less so because of the size of the wave that is very high. Tsunami wave properties are shallow water even in the deep sea. (9.8 m/sec 2) and the depth of the water, for example, in the Pacific Ocean with a depth of approx. 4,0 meters waves at speeds of approximately 200 meters per second, or 720 kilometers per hour. Best coast at a depth of 40 m, the wave will have a slower speed remains 20 meters per second, or 72 kilometers per hour
