TSUNAMIThe word “tsunami” comes from the Japanese language meaning Great Waves (Tsu: port and Nami: wave). Adapan agreed definition many people is a tsunami is a natural disaster caused by rising sea waves to the mainland at high speeds due to the earthquake centered under the sea.The quake could have been caused by soil erosion, the plates were shifting,volcanic eruptions and who experienced meteor that crashed in the ocean.This usually happens when the tsunami earthquakes exceeding magnitude7 on the Richter scale. Tsunami is quite dangerous, especially for thosewho live in Area beach. With great power, he will sweep everything in its path.When talking about the tsunami, then we would have to start from thecause, namely the earthquake in the ocean. Tsunami always preceded a powerful movement that we commonly call the earthquake. Although it isknown that there are various types of this earthquake, but 90% of thetsunami caused by the movement of the plates in the earth that happened to be located in areas of the oceans. It should be also mentioned, thehistory of tsunamis ever recorded due to the eruption of Krakatoa. An earthquake in the bowels of the earth will result in the emergence of  pressure to the vertical direction so that the bottom of the sea will rise and  fall in a short time span. This will then lead to an imbalance in the oceanwater which is then pushed into a large wave that moves reached themainland.With great power there in the water waves, naturally if the buildings onthe mainland can be washed away easily. The tsunami waves propagateat speeds unimaginable. He could reach 500 to 1000 kilometers per hourat sea. And when it reaches the shore, the speed is reduced to 50 to 30kilometers per hour. Although reduced rapidly, but the pace was able tocause severe damage to humans. If we look at the tsunami, of course we understand that there is no humanintervention in it. Thus, we do not have control to prevent these causes. However, the preparation and maximum vigilance, we can minimize theimpact of the tsunami itself. A good example has been shown in Japan. Although prone to tsunamis, but the awareness of people able to reducethe number of victims of the disaster.
