Tsunamis are one of the most dangerous natural disasters known to mankind that cause devastating effects on society. Despite the fact that tsunamis are not frequent phenomena, it causes huge causalities once it occurs. The number of deaths could reach 420 thousand a year, accompanied by the destruction of many costal residences. But despite the fact that tsunami damages are inevitable, it can be reduced. The word tsunami was originated from the Japanese words “Tsu” meaning “harbor”, and “Nami” meaning “wave”. It is believed that ancient Japanese sailors used this word because they were able to predict the arrival of Tsunami huge waves from observing the unusual wave activity nearby harbors. But that is most likely untrue because predicting the time and location of an upcoming tsunami is nearly impossible till this very day (Bernard et al. 3). In the past, there was some kind of confusion between tsunami and other phenomena that generated similar large waves such as storm waves. Some other people used to think that the tsunamis were tidal waves that are caused by the gravity of the moon and the sun due to the similarity in its appearance to the tides. However, the origin of tsunami differs greatly from the origin of the tides. A tsunami can be generated from different sources (Cartwright and Nakamura 152). Submarine volcanic action is one of the sources that can generate tsunamis, yet, most of it are born when plates forming earth crust starts moving. The lighter continental plates bury the dense oceanic plates resulting in an abrupt shaking of the ground, a phenomenon known as earthquakes. Most of which are violent but despite how big or small an earthquake is, all are able of generating devastating tsunamis as long as it occurs... ... middle of paper ... ...the Term and of Scientific Understanding of the Phenomenon in Japanese and Western Culture.” Notes and Records of the Royal Society of London, 62.2 (Jun. 20, 2008): 151-166.

Imagine if a 9.0 earthquake struck the West Coast today, resulting in a giant tsunami. Coastal towns would be washed away or completely isolated, and electricity would be lost (FOX5). There would be $70 billion in damage and people would only have 15 minutest to evacuate or move to higher ground resulting in 10,000 deaths (FOX5). This sounds like a plot for a scary movie, but this is actually a reality. The Oregon Coast in located on a subduction zone, which makes it very susceptible to major earthquakes and tsunamis. With the Cascadia subduction zone running along he West Coast the threat of a major tsunami is very real.
Meica Rogue waves and tsunamis have two things in common, they both come from water, and they are destructive. The topics are rogue waves, tsunamis, and the difference. Rogue waves and tsunamis are caused in the water but are in different part of the ocean. Tsunamis are formed in the Pacific Ocean and rogue waves are formed in the Indian Ocean.

The 2004 Indian Ocean earthquake and tsunami took place on December 26th, 2004 and had a magnitude of 9.15. The cause of the Sumatra Tsunami was due to the sliding of two tectonic plates. Sumatra, an island in Indonesia, is situated on the boundary of the two plates; part of Sumatra is situated on the India/Australian plate and the other part is on the Eurasian plate. The Indian/Australian plate and Eurasian plate connect on the ocean floor at the boundary, a little over 100 miles off the short of Sumatra. Sumatra was one among the many countries that was impacted by these natural disasters. To fully understand the Sumatra Tsunami one must examine the events that led up to it, what a tsunami is, and the damage caused.
To determine how the fire prevention systems in a structure weather an earthquake, a test was conducted at the University of California, San Diego, in 2012. The test was preformed outside on a 5 story building, located on an

Additionally, this earthquake occurred on a thrust fault. This fault was a subduction zone slip which occurred primarily beneath the ocean were the Pacific plate plunges underneath the North American plate. This sudden upward movement of the sea floor along the rupturing fault generated a massive tsunami. This vertical deformation

Second, the two natural occurrences have differing causes. Rogue waves are often caused by wind strength, ocean currents and obstacles such as islands or large rocks in the way of the waves. Another main way they are caused are by colliding currents, which may solve the mystery of disappearances in the Bermuda Triangle. Tsunamis are caused by very different factors. Tsunamis begin when something upsets the ocean, usually landslides, earthquakes or volcanoes. Then this causes a ripple effect, and as they near shore, the waves build up. Clearly, tsunamis and rogue waves are very different in
The Tohoku earthquake caused by the movement of the Pacific plate slides underneath the Eurasia plate at the rate of three inches per year, associated with Japan Trench
The word “tsunami” comes from the Japanese, in which “tsu” stands for harbor and “nami” means wave. Another name for tsunamis are seismic sea waves. A tsunami is defined as an ocean wave with long wavelengths that are produced by a landslide, volcano, or earthquake. After a tsunami is generated, the waves move very rapidly across the ocean, reaching speeds over 435 miles per hour. In open and deep waters, a tsunami may have a wavelength of 125 miles and a height around 1.5 feet making it almost impossible to recognize. However, when a tsunami hits shallower waters, the height of the wave starts to increase. Shallow waters cause the waves to slow down, which results in a shorter wavelength. Once a wave reaches the shoreline, a tsunami can amazingly reach as high as 130 feet up in the air. Often, tsunamis are mistaken as tidal waves, but they are not the same thing. Tidal waves are ocean waves like tsunamis, but tidal waves take place in shallow waters
...d out the leakage a year later. Another cause of the disaster is that government ignored the chance of tsunami. Scientists warned about the dangerousness of tsunami, and advised them to build more protection to tsunami threatening. However, the government did not consider the advise (IAEA, 2011)
There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
