Tsunami and Their Effects

             Throughout the world, there are many forces of nature, which contain massive destructive power. At any given point in time, somewhere on the globe, there can be earthquakes, tornadoes, floods, heatwaves or even volcanic eruptions, to name just a few. One of the most feared of all the naturally occurring destructive forces is the tsunami.
             The word tsunami is of Japanese origin. The word "tsunami" is both singular and plural. It literally translates to "Harbor Wave". The name "Harbor Wave" is a bit misleading due to the fact that tsunami are not restricted to harbors and can affect any coastline structure. Many English-speaking people also call tsunami "Tidal Waves". The term "Tidal Wave" is likewise a misnomer because "Tidal Waves" are not caused by the tides and are unrelated to the tides, although tide level can alter the amount of runup (flood level caused by tsunami) on coastal areas.
             The phenomenon known as a tsunami is a series of waves of extremely long wavelength and long period, generated in a body of water by an impulsive disturbance that displaces a large amount of aforementioned water. The displacement of water can be a result of many naturally occurring geological and meteorological events, as well as a few man made events. Earthquakes are the most common cause of tsunami, followed by landslides, volcanic eruptions, and meteorite impacts. Air, surface, and subsurface detonations of large yield nuclear weapons can also vaporize enough seawater to cause tsunami.
             An earthquake-generated tsunami occurs when an earthquake causes a deformation of the seafloor, which will cause a corresponding displacement of the overlying seawater from its equilibrium position. Waves are generated as gravity pulls the displaced seawater back to its equilibrium position. The size of wave generated will be directly proportional to the amount of vert...
