其实，英语中的这个词“Tsunami”是从日语中来的。主要原因：1946年に起きたアリューシャン地震の际、日系移民が用いたことからハワイで「Tsunami」の语が使われるようになり、アメリカでも広く用いられるようになったため、「Tsunami（津波）」は国际语となった。英语にも「津波」を表す「tidal wave」という语があるにもかかわらず「Tsunami」が用いられるのは、上记経纬のほかに、「tidal」は「潮」を意味する言叶であり、津波が満干によって起こる现象ではないためと考えられる。这是“津波”这个词的由来。上面大概说的是，1946年阿留申群岛发生地震的时候，当地的日本移民说的“Tsunami”这个词就在夏威夷被使用了，再由于在美国被广泛使用了之后，“Tsunami（津波）”这个词就被国际化了。尽管在英语中表示“津波”这个意思的说法有“tidal wave”，但是“Tsunami”这个词也在被使用。原因不光是上面讲的，还有就是“tidal wave”中的“tidal”是海潮的意思，而“津波”所表达的现象不是有潮汐所引起的。

tsunamitsunami是一个外来语，是日语单词，表示“海啸，由海底地震或火山喷发而造成的巨大海浪”。Tsu在日语中表示“岛屿，港口”，nami表示“海浪，浪花”。下面是一段英文的介绍~~~A tsunami is a huge sea wave that forms mainly in the Pacific Ocean area. People die and property is destroyed when a tsunami hits land. What causes these dangerous sea waves? Sometimes, tsunamis are caused when earthquakes take place underwater. Then, water begins to move up and down from the top of the ocean right down to the bottom. Waves begin to form, and each wave is called a tsunami. A tsunami is less than one meter high and can move at speeds of almost 800 kilometers per hour while it is far out in the ocean. But the tsunami rises much higher and moves more slowly as it comes closer to land.The weather bureu warns people over radio and television stations when a tsunami is heading for land. These warnings have helped save many lives.

海啸的形成( The formation of the tsunami ): 海啸是一种具有强大破坏力的海浪。当地震发生于海底，因震波的动力而引起海水剧烈的起伏，形成强大的波浪，向前推进，将沿海地带一一淹没的灾害，称之为海啸。 A tsunami is a powerful destructive waves. When the earthquake occurred in the bottom of the sea the driving force of the shock wave caused by the dramatic ups and downs of sea water the formation of a strong wave to move forward and coastal zones-flooded disaster called tsunami. 海啸的影响( Effects of the tsunami ): 虽然台湾亦处环太平洋地震带，不过和日本不同，台湾很少有海啸侵袭。主要原因是海啸多来自太平洋的海底地震，会从台湾东部靠近，而在台湾东部的海底，菲律宾海板块和欧亚板块交界处，海底地形非常陡峭，容易使波浪受到折射而远离，不利海啸成形。2011年日本东北大地震（海底地震）台湾仅观测到10公分潮差。 一般认为台湾最可能发生海啸的地方是基隆到宜兰一带沿海。但万一中国南海一带的地方出现大地震，势必会对台湾西南沿海、中国东南沿海、中南半岛、菲律宾等地造成海啸威胁。 虽然南中国海发生大规模地震机率非常低，不过台湾仍有学者提出马尼拉海沟恐有潜在危机。 Although Taiwan is also the circum-Pacific sei *** ic belt but unlike Japan there is little tsunami. The main reason is the undersea earthquake tsunami e from the Pacific Ocean from the eastern part of Taiwan near the seabed in the eastern part of Taiwan the Philippine Sea Plate and the Eurasian plate at the junction of the seabed topography is very steep easy to make waves by refraction away from the adverse tsunami shape. The earthquake of 2011 in northeastern Japan (undersea earthquake) Taiwan is only observed 10 cm tidal range. Is generally believed that Taiwan is the most likely place of the tsunami along the coast of Keelung to Yilan. However in case the place of the South China Sea in the vicinity of the earthquake bound to have Taiwan's west coast southeast coast of China Indochina the Philippines caused by the tsunami threat. Although the South China Sea large-scale earthquake probability is very low but there are still scholars in Taiwan asked the Manila Trench fear of a potential crisis. 参考: google *** Tsunami is generated when the sea floor abruptly deforms and vertically displaces the overlying water.Tectonic earthquakes are a particular kind of earthquake that are associated with the Earth's crustal deformation; when these earthquakes occur beneath the sea the water above the deformed area is displaced from its equilibrium position.a tsunami can be generated when thrust faults associated with convergent or destructive plate boundaries move abruptly resulting in water displacement owing to the vertical ponent of movement involved. Movement on normal faults will also cause displacement of the seabed but the size of the largest of such events is normally too *** all to give rise to a significant tsunami. 参考: ***
