英语翻译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.受台风和低气压的影响,

The tsunami was a catastrophic waves,usually by the source within 50 km under the sea,above the Richter magnitude 6.5 undersea earthquake.Affected by the impact of typhoons and low pressure,the sea will lead to waves,sometimes up to several meters,but the wave of increase is limited,from a few meters to several hundred meters,so the amount of impact on the shore of the sea water is limited.The tsunami is different,although the tsunami in the distant sea only a few centimeters to several meters high,but because of surface uplift of the range,and sometimes hundreds of kilometers wide tsunami,this huge "water block" produced by destructive is very large,serious harm to the shore of the buildings and human life.According to the survey,
The Indian Ocean tsunami in Thailand and the coast to a 50-ton boat from the sea onto the shore 1.2 km away.From the data,the tsunami of up to 2 meters,wooden houses will be instantly destroyed; tsunami as high as 20 meters of reinforced concrete buildings are also overwhelmed.
One characteristic of the tsunami is fast,the earthquake took place in deeper water,the faster the tsunami.The deeper water because of seabed changes in the amount of water surging more thus giving rise to the sea after the tsunami,the faster the move.If the local depth of the earthquake of 5000 meters,the tsunami and the jet velocity is similar to 800 kilometers per hour,move to the depth of 10 meters,speed slow down,into 40 km.As the former waves slow down,push came after the waves overlap,so the tsunami waves to the shore increased,if the coastal seafloor topography was V-shaped,set off the tsunami waves will be higher.
Moving in the distant sea is extremely close attention to the rapid pace of close to land,to reach the coast of a sudden a huge wall of water formed,which is the tsunami,people discovered that it was too late when you would run away again,so the event of an earthquake should immediately leave the coast,to the height of a safe place.
Shortly after the severe shock,waves roar,to pull Xiu reminders dry trend across the coastline,across the fields,rapid attacks on the shore of the cities and villages,transient people have disappeared in the waves in the.All the port's facilities,Tsunami earthquakecollapsed buildings,the looting in the turbulent,and be swept bare.Later,on the beach a messy,full of broken plates and human and animal residues wooden body.The earthquake and tsunami disaster has brought to mankind is enormous.At present,the human earthquakes,volcanoes,tsunamis and other sudden disaster,only through the forecast,observation to prevent or reduce damage caused by them,but it can not control them from happening.
