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,海面会掀起巨浪,虽然有时高达数米,但浪幅有限,由数米到数百米,因此冲击岸边的海水量也有限.而海啸就不同了,虽然海啸在遥远的海面只有数厘米至数米高,但由于海面隆起的范围大,有时海啸的宽幅达数百公里,这种巨大的"水块"产生的破坏力非常巨大,严重危害岸上的建筑物和人的生命.据调查,这次印度洋大海啸在泰国沿岸把一艘50吨重的船从海边推到岸上1.2公里远的地方.从有关数据来看,海啸高达2米,木制房屋会瞬间遭到破坏；海啸高达20米以上,钢筋水泥建筑物也难以招架.
海啸的特征之一是速度快,地震发生的地方海水越深,海啸速度越快.海水越深,因海底变动涌动的水量越多,因而形成海啸之后在海面移动的速度也越快.如果发生地震的地方水深为5000米,海啸和喷气机速度差不多,每小时可达800公里,移动到水深10米的地方,时速放慢,变为40公里.由于前浪减速,后浪推过来发生重叠,因此海啸到岸边波浪升高,如果沿岸海底地形呈V字形,海啸掀起的海浪会更高.
在遥远的海面移动时不为人注意,以迅猛的速度接近陆地,达到海岸时突然形成巨大的水墙,这就是海啸,人们发现它时再逃为时已晚,因此,一旦发生地震要马上离开海岸,到高处安全的地方.
剧烈震动之后不久,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,瞬时人们都消失在巨浪中.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.地震海啸给人类带来的灾难是十分巨大的.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 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.
