tsunami

it´a composed by two japanese word: tsu (harbour) and nami (wave) so, it means wave of harbour.
it´s a group of enormous waves with lot of energy and size. it cause big damages, economic loss and, the much of times, death.
it´s pruducted by an acuatic heartcuarter
its energy depens of the height, speed and the dintance where it was made.

according to wikipedia there were 12 known tsunamis: santorini 1650, lisboa 1755, krakatoa 1883, mesina 1908, pacific 1946, alaska 1958, valdivia 1960, tumaco 1979, nicaragua 1992, hokkaio 1993, indic 2004 and contitution2010. wikipedia says more thing but it´s too long for read so i´m going to change the web page that says what you must made in case of this.
-first, there is a big tremor that can broke walls. this is a natural advertisement that says you must go away quickly ang get over 30 meters from water, if not, you will be swamming with the noise IN the water.
-you also have to note it to the others in the area, but think, this is a natural selection, only the wise men could be safe (some think that it´s a bit cruel but.... what do you prefer die the others or you?)
- next, if you haven´t follow the first advice, you could see the water level is decreasing. here this page (http://www.angelfire.com/nt/tsunamis/#%BFQU%C9+HACER) says you must run very very very ..... fast, over 100km/h (the wave speed) or you will die.
-it mencionates too if you are in the sea about 6 km of coast nothing will hapenned to you, if you are nearer you can do your will.
-the tsunamy can have more than 12 waves so, don´t be stupid and return when the first arrive, wait a little more.
it coments more things but them aren´t very important.

in conclusion, if you are on holidays and you think will there be a tsunamy soon, run and complain after.
