What causes tsunamis

 How are tsunamis caused


Introduction


A tsunami is a giant wave that causes massive destruction and force that can kill   people.  They are made by earthquakes, volcanic eruptions or meteor strikes.


The purpose of this explanation is about what causes tsunamis.


Facts,1,2,3


Tsunami the word is actually a Japanese word and in english it means harbour wall, Tsunamis can be  10X bigger than a normal wave and when it hits the shore it slows down up to 50 KM/H (31 MPH) and while the tsunamis coming, the back end seeps deeper in the sea causing the tsunamis height to increase, today we have early detection systems that can detect tsunamis from far away.


PARAGRAPH 1


Tsunamis aren’t normal waves because they are 10X higher than a normal wave at the beach that you usually see, however tsunamis are giant and destructive and create lots of force which can destroy coastal cities. People are foolish sometimes but when a giant tsunami comes people just go to check it while you are risking your life when it comes at you super quickly and might die or drown.


Detection systems


People can get alerts or the if you don’t have your phone you can see that the tide has gone out or there has been a very strong earthquake that is the sign that there may be a tsunami that is going to hit because then they can leave early and when everybody has evacuated, citizens might have to go to the highest point of a hill and just wait for the tsunami to pass or just go to another city and when it’s over they can return to their homes.










Steps of how a Tsunami forms



The first step of a tsunami is that if something violent happens like earthquakes, volcanic eruptions, meteor strikes happen the back of the tsunami seeps deep in the sea giving it height. The second step that the tsunami gains speed and reaches the shore, going as 50 KM/H and then the 3rd step is that when it reaches the back goes deeper and deeper into the sea giving it more speed and height and causes massive destruction and deaths on coastal cities.





Conclusion



Most tsunamis are caused by earthquakes, volcanic eruptions and meteor strikes and cause massive amounts of death and  destruction.
