Tsunamis

A tsunami is a huge wave that can destroys citys, towns... near of the sea.
They are destructives with 7.5 or more points in the Richter scale. For escape from a tsunami, you must see a few minutes before the following signals:
-Suddenly, there are very low tide.
-The animals run very quickly to the high parts.
-You can notice an earthquake that can broke walls, the glasses and plates fall...
-If you go in a boat and you are far (6 kilometers or more), you can go more far for prevent the waves, but you are safe. If you are far of the coast but you are suimming, you can't do nothing.
If you don't notice it, there isn't a tsunami (or you are sleep and you don't realise). If you can run and be safe, wait, because a tsunami isn't a huge wave only. It's a lot of enormous waves (4, 5, 6...) that can kill you all alike.
In conclusion: if you are in the sea and you notice an earthquake (if it isn't your friend jumping on you), run and don't wait for be more brown.
