What is a Tsunami? A great wave caused by an underwater earthquake or by volcano deep in the sea. A tsunami is a series of traveling ocean waves of extremely long length generated by disturbances below or near the ocean floor. Tsunamis can grow up to 1,500! Knowledge from The New Book of Knowledge and The Earth Pack

Where does my Disaster Typically Occur? It normally happens in the Pacific Ocean because there’s the most volcanic and earthquake action there. For example, on the U.S. coastline it happens most destructively on California, Oregon, Washington, Alaska, and Hawaii. As well as many times on the Indian Ocean for the same reasons. Tsunamis By: Luke Thompson

How Often Tsunamis Occur Tsunamis will occur about twice a year that are destructive to land. On estimate, every 15 years an ocean-wide tsunami will burst into action. Here is a chart of a tsunami on May 23, 1960 on an island of Hawaii. It shows how high and low each wave is. Pay attention to the Increase and decrease in the wave height. inhttp:// ami+chart&um=1&hl=en&client=firefox- a&rls=org.mozilla:en- US:official&biw=1366&bih=664&tbm=isch&tbnid =RO_nlMOaOkRbpM:&imgrefurl= gs.gov/circ/c1187/&docid=AhpBao7Q5lkq- M&imgurl= s/fig17.jpg&w=580&h=441&ei=Se0zT4K_A8eftwel wazFAg&zoom=1&iact=hc&vpx=181&vpy=316&dur =3773&hovh=196&hovw=258&tx=184&ty=140&sig = &page=1&tbnh=136&tbn w=179&start=0&ndsp=18&ved=1t:429,r:6,s:0

What Structures of the Earth are Involved with Tsunamis Tsunamis will happen many times in the Pacific Ocean, and the Indian Ocean LOTS of times, for example the 2004 Sri Lanka Tsunami that killed around 220,000 people. Some tsunamis will happen on coastlines. Citation:

What Typically Happens To me too many bad things happen in a tsunami. They start with an earthquake on the ocean floor. Tsunamis can get up to 1700 feet high. A tsunami isn’t one wave, but a chain of waves. And the first one is rarely the biggest; or the last. They are like non-stop floods; they keep coming. Citation: Tsunami hits Sri Lanka " The Gale Encyclopedia of Science. Ed. K. Lee Lerner and Brenda Wilmoth Lerner. 4th ed. Detroit: Gale, Gale Science In Context. Web. 8 Feb

What would be the Worst-Case Scenario for a Tsunami Well the tallest one like a said earlier was around 1,500 feet tall which would probably kill about 220,000 people. The tsunami could have so many waves it will also cause floods, and possibly after shocks from an earthquake that caused the tsunami. Here is the 1700 foot in Alaska t+wave+alaska&um=1&hl=en&client=firefox- a&sa=N&rls=org.mozilla:en- US:official&biw=1366&bih=664&tbm=isch&t bnid=r- ZZE2uGv0EjMM:&imgrefurl= underground.com/blog/weatherhistorian/ar ticle.html%3Fentrynum%3D15&docid=ccDlx qgd5pLbiM&imgurl= und.com/hurricane/chrisburt/lituya.jpg&w= 640&h=481&ei=POgzT5f4M8KhtweM0OXU Ag&zoom=1&iact=hc&vpx=737&vpy=153&du r=1234&hovh=195&hovw=259&tx=144&ty=87 &sig= &page=1&tbnh =134&tbnw=178&start=0&ndsp=18&ved=1t:42 9,r:3,s:0

How do you Measure a Tsunami There really isn’t a rating for tsunami intensity except how high the tsunami gets. You could measure with the Richter Scale for earthquakes if the tsunami was caused by an earthquake. ttp://lh6.ggpht.com/_8NJt8BSZEjM/TX6F 9nFlyeI/AAAAAAAABSY/5ztni6BwPCI/Ea rthquake_Richter_Scale%255B3%255D.jpg &imgrefurl= TjhaG_GITzoE3iX_mbU2LyNc=&h=524& w=705&sz=149&hl=en&start=1&zoom=1&t bnid=E- cc1Tn7sPyHNM:&tbnh=126&tbnw=170&ei =HfAzT8TMMNCUtwfl9PXTAg&prev=/se arch%3Fq%3Dthe%2Brichter%2Bscale%2 6um%3D1%26hl%3Den%26client%3Dfiref ox- a%26sa%3DN%26rls%3Dorg.mozilla:en- US:official%26imgrefurl%3Dhttp://ginosb log.com/2010/02/28/understanding-the- richter- scale/%26imgurl%3Dhttp://ginoraidy.files.wordpress.com/2010/02/earthquake_richt er_scale.jpeg%26w%3D705%26h%3D524 %26sig%3D %26nd sp%3D21%26biw%3D1366%26bih%3D664 %26tbs%3Dsimg:CAQSEgkyXewp8K7DjiG lMYAUK9ZeCg%26tbm%3Disch&um=1&it bs=1&iact=hc&vpx=177&vpy=180&dur=333 &hovh=193&hovw=260&tx=182&ty=150&si g= &page=1&ved=1t :429,r:0,s:0

After Affects Associated with a Tsunami Flooding would be a problem after the tsunami because it would take a long time to cover. Debris from the tsunami taking stuff and throwing it down to earth. Definitely home destruction would be a BIG problem.

Facts and History Tsunamis have been around since 426 B.C. The Largest ever recorded earthquake that made a tsunami was in Sri Lanka The earthquake was a 9.5 magnitude on the Richter Scale. Not even the Japan tsunami that just happened can top that!
