Tsunamis

  On Dec. 26, 2004 most people will never forget that day. It started when there was a powerful earthquake at the bottom of the Indian ocean.Then a giant wave that people call a tsunami covered the hole place.When the tsunami hit the shores of the islands it killed over 145,000 people.At this point scientist are useing new tecnology to find where they are going to be and how they will change earth. Tsunami can occur at any time of the day. In some areas the height can be as great as 30 feet or more, and they can move several hundereds of feet. When a body of water is rapidly displaced a series of waves are created. the rapid displacement of the body of water takes place due to the following resons: volcanic eruption, earthquakes, underwater explosion, large meteorite impacts, mass movements above or under water. At the deepest point of the ocean is were the Tsunamis can have a speed of 600mph. An estimated 1,600 are dead, crushed, or pulled to sea and drownded as the mighty waves whithdrew. If the waves range from 40 meters to more than 100 meters, they are called a "megatsunami". When they reach land, they acquire more height due to the force of impact. Tsunamis that strike coastal locations in the Pacific Ocean Basin are almost always caused by earthquakes. When it reaches land, it may like a series of breaking waves or a large, powerful wave called a bore. When tsunamis are heading for the island the people at the beach can usually can tell if it is heading for land. Cause it's so big in size you proble could see it shore to about 3 miles or enen longer depends how large it is. Some people like the weather man tells you if it and when will it be here by the picture up there. People usally get out of town when they say that kind of stuff on tv because they know there going to get killed if they don't get out. Waves can get up to as high as 100 feet and people should get out if they ever see one because they cause a lot of damage because of flooding. A tsunamis crosses the pacific ocean in 24 hours. A tsunami can be a series of waves. The first wave is the less intense of all. Tsunamis can travel up rivers and streams that lead to the ocean. Tsunamis are large, rapidly moving ocean waves triggered by a major disturbance of the ocean floor. They are usually caused by an earthquake but sometimes can be produced by a submarine landslide or a volcanic eruption. Giant forces that had been building up in the Earth for hundreds of years were released suddenly on December 26, shaking th ground violently and unleashed a series of killer waves that sped across the indian Ocean at the speed of jet airliner. By the end of the day more than 150,000 people were dead or missing.

how often do tsunamis waves happen? Tsunamis hppen far more than most people realise. Hawai sees small tsunami ever year and Alaska, Californai, Oregan, Washington, Japan, Indonesia, Malaysia, Philipines, India and other parts of the world can all experience larger or smaller tsunami in the future. Tsunami earthquakes are those where there is a major shift of the seabed as two tectonic plates slide against each other, releasing forces many times as great as an undersea neclear bomb.

What is a tsunamis? How are Tsunamis formed? Tsunamis are caused by sudden movement of the bed, during an earthquake or a volcano. The result is a ripple of waves, just as if you dropped a large stone into a pool. Tsunamis don't usally cause any troble at that stage to ships or boats. Thats because the water is deep and the waves are long.

How does a tsunamis work? A tsunami is a is a series of waves when a body of water, such as an ocean is rapidly displaced on a massive scale. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, and large meteorite impacts all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating.
