The characteristics of waves
.Tsunami is different from water waves is very simple. The waves can travel long distances without losing energy. And can destroy the coast are far from the origins of thousands of kilometers.Will travel much slower vibration of earthquake wave is traveling in the ground. Therefore, the wave may match the impact after people around feel an earthquake for several hours
.
.The waves are generally significant properties measured in two reasons, and which is ระหว่างลูกคลื่น two balls, and the wavelength, which is the distance between the two waves. In the open sea a tidal periods for a long time.At the same time, it has a very long wavelength By may long to hundreds of kilometers. While the general wave caused. The wind is about 10 coast period seconds and wavelength around 150 meters only.Tsunamis are fast moving, since 500 to 1000 kilometers per hour. However, when into the coast with depth decreases. The waves will be reduced speed and start the formation wave is high by may have a height of more than 30 m
.Tsunami will move out of the source, so the coast sheltered by the landfall and the other is safe from the wave, however. There is also a chance that the wave can turn ben to affect.By strength of will depend on the origin and characteristics of the landscape area
.
.The wave behavior should be a "shallow water wave". When the ratio between the depth of the water and the size of the waves is low. So, due to the size of the wave is very high. The tsunami was qualified as a shallow water wave, even in the deep sea.(9.8 meters / second 2) and depth of water. For example, in the Pacific Ocean with a depth of about, 4000 m wave are fast moving about 200 per second, or 720 kilometers per hour. The coast has the depth 40 meters. Wave speed is slow left 20 per second, or 72 kilometers per hour.
