Tsunami

Recently, the earthquake hit Indonesian again, exactly in Aceh. This is the second time for Aceh which had hit by earthquake. When the first earthquake, it’s not only just earthquake but also the tsunami after it. Now, I want describe what the tsunami is.
Tsunami is a series of huge waves that can cause great devastation and loss of life when they strike a coast. Tsunami are caused by an under water earthquake, volcanic eruption, etc. Most tsunami are caused by under water earthquakes, but not all under water earthquakes cause tsunami. An earthquakes has to be over about magnitude 6,75 on the richter scale for it to cause tsunami, about 90% of all tsunami occur in the pacific ocean.
This kind of natural disaster gives a bad effect for all. The great waves that are producedcan cause tremendous damage for island and destroy all surrounding.
