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 meter
