海啸的影响英语

Tsunami forced a large scale movement of the islands, which devastated the diversity of the Ocean's ecosystem. Human activities lead the Tsunami ....翻得不好，勉强着看。。O(∩_∩)O~呵呵

海啸的起因 海啸是一种灾难性的海浪，通常由震源在海底下50千米以内、里氏震级6.5以上的海底地震引起。水下或沿岸山崩或火山爆发也可能引起海啸。在一次震动之后，震荡波在海面上以不断扩大的圆圈，传播到很远的距离，正象卵石掉进浅池里产生的波一样。海啸波长比海洋的最大深度还要大，轨道运动在海底附近也没受多大阻滞，不管海洋深度如何，波都可以传播过去。 海啸的危害 地震海啸给人类带来的灾难是十分巨大的。剧烈震动后，巨浪呼啸,以催枯拉朽之势，越过海岸线，越过田野，迅猛地袭击着岸边的城市和村庄。港口所有设施，被震塌的建筑物，在狂涛的洗劫下，被席卷一空。事后，海滩上一片狼藉，到处是残木破板和人畜尸体。目前，人类对地震、火山、海啸等突如其来的灾变，只能通过预测、观察来预防或减少它们所造成的损失，但还不能控制它们的发生。The causes of the tsunami Is a catastrophic tsunami waves, usually by the source on the seabed within the next 50 kilometers, more than 6.5 Richter scale earthquake in the seabed. Underwater or coastal landslides or volcanic eruptions can also be caused by the tsunami. In a shock, the shock wave in the sea in order to expand the circle, spread to great distances, as pebbles falling into the shallow waves generated by the same pond. Tsunami wavelength than the maximum depth of the sea also, and orbital motion in the seabed near the block did not by much, no matter the depth of the ocean, the wave can be spread over the past. Tsunami hazards Earthquake and tsunami disaster to humanity is enormous. After rattling, roaring waves to loose rotten tendency to cross the coastline, across the fields, the rapid attack of the shore towns and villages. All port facilities, the collapse of the buildings collapse, officials in the looting of狂涛was swept out. After that, the beach a mess everywhere residual wood panels and broken bodies of humans and animals. At present, the human earthquakes, volcanoes, tsunamis and other sudden disaster, the forecast can only be observed to prevent or reduce the losses caused by them, but they can not control the occurrence.

tsunami is usually caused by strong earthquakes that happen in oceans.great sea waves will be pushed towards the shores with great speed.if the people along the shores don't know tsunami is coming,they will suffer great damage.for example,the tusnami,which happened in the indian ocean on december 26,2004,killed more than 150,000 people in indonesia,sir lanka,india,thailand and other countries.millions of people were injured and became homeless.tsunami is a natural disaster.we should set up more advanced warning systems along the shores,on the islands and in man-made staellites.besides,we should protect our oceans further instead of destroying them.
