Introduction Mistakenly called "tidal wave" the word tsunami is a Japanese word meaning‚ "harbor wave". A tsunami is a series of traveling ocean waves of extremely long length generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Tsunamis are primarily the result of a vertical displacement of water and rank high on the scale of natural disasters. Since 1850‚ tsunamis have been responsible for the loss of over 440‚000 lives and billions of dollars

Personally I would start with the first recorded tsunami‚ which if wikipedia is right was as far back as 426 BC. To me that is shocking because I hadn’t heard of Tsunamis until late 1990’s‚ so the fact that this isn’t a "new" phenomenom is a little surprising to me. Then I would have a small paragraph on what causes tsunamis. Then I would decide since you only have 2000 words if I want to focus on the dollar destruction‚ the lives destruction‚ or the infrastructure destruction. You may be

The Causes of Tsunami All tsunamis are caused by the sudden displacement of large volumes of water. All are the result of violent events with enough power to displace large volumes very rapidly. Moreover‚ Tsunamis are often referred to high waves of water caused by changes in the flow and surge of the ocean. On the other hand‚ Tsunamis can be caused by a few different factors‚ which are an earthquake‚ a large-scale undersea landslide‚ a submarine volcanic eruption (Cause of Tsunami‚ n.d.).

Multiple Wave Damage * Tsunamis arrive with multiple waves‚ with the stronger ones typically arriving after the first one hits. Given the shape of the underwater shore‚ significant amounts of water get pushed upward and higher at the coast‚ allowing the tidal water to flow higher than it normally would. Anything that is loose on the ground gets swept up and bounced around like cork. Because water is so heavy as a mass‚ it can move cars‚ wood‚ metal‚ cement‚ and debris. All of this material with

Sometimes known as a killer wave‚ this huge surge of water is the product of two forces colliding. Earthquakes‚ when mixed with the ocean‚ can have a devastating effect on structure and society. An earthquake can cause buildings to fall‚ start a fire‚ and block roadways‚ as well as start a tsunami. Together‚ these forces can destroy homes‚ leaving many people homeless.
