What is a tsunami
Indian Ocean region has seen a huge earthquake with a magnitude of nine on the Richter scale, the quake was followed by a phenomenon known as "tsunami" caused widespread destruction and killed tens of thousands of people. What is this phenomenon
Label
Japan origin of the word) meaning "harbor wave" (Port = settled = 津) (wave = Nami = 波), and launched by Japanese fishermen when they noticed the destruction at their ports Igm flights of fishing did not feel the sailors with a surge over them during their fishing tide outbreaks walk toward the beach under the water and its impact on the water surface may not have mentioned the length of the tidal wave up to 100 km
What is this phenomenon
Tsunami is a series of sea waves fast and powerful that result from earthquakes or volcanic eruptions or the fall of meteors from outer space in the seas and oceans.
Are common phenomenon of the tsunami in the Pacific region, where more than half of the volcano in the world. When are the new phenomenon, the coastal areas are without prior notice in some cases, the waves of very powerful. They can wave to carry rocks from the walls repel the waves, weighing twenty tons, and to throw them for a distance of twenty meters
What is the difference between tsunami waves and the normal sea
And reach a speed of tsunami in the Pacific Ocean to 800 km per hour. If an earthquake occurred in the city of Los Angeles, up the tsunami to the Japanese capital Tokyo in less time than it takes flight between the two cities with a jet.
The difference between tsunami waves and the normal sea is that the energy derived from the first movement of the earth and not from the wind. With the length of the tsunami (ie, the distance between the crest of a wave and bottom) to a hundred kilometers, and the time between one tsunami and the subsequent wave of up to an hour
Tsunami, a huge wave
Tsunami, a huge wave on the ocean contains a series of waves and an enormous amount of water caused by earthquakes, volcanoes, etc., and created the tidal wave when there is a vertical slide at the bottom of the sea would undermine the lateral surface of the seabed arise on the sea surface tidal wave and, like any router, turn the tidal wave to beaches and depends on the size of a landslide at the bottom of the sea, is determined by the quantity and size of the tidal wave and the amount of devastation they inflict
Causes
Created the tidal wave occurrence of earthquakes and volcanoes, or even collision of celestial bodies large-scale sea, and tidal waves arise when the compatibility of the bottom of the sea change as a result of natural variations such as earthquakes, etc, and the occurrence of either convex or concave in the bottom of the sea which caused disruption in the amount of water over the affected area
Specifications
Different tidal waves of the seas and oceans resulting from the movement of wind, then you can first cross thousands of kilometers in the bottom of the sea with a slight loss of wave energy as a result Trahalha, and to this, we find that the impact of the tsunami Almroy see after hours of their occurrence in the bottom of the sea on the beaches affected after the application of amounts enormous water on land
Monitor changes
Ensure a lot of countries along the Pacific Ocean basin, such as Japan and the Hawaiian Islands to monitor changes in water pressure at the bottom of the ocean and to send these changes via satellite to monitoring centers tidal waves to enable the authorities to evacuate the beaches of the people, which was not available in the incident in the Indian Ocean earthquake 2004, On December 26, 2004, a tsunami hit the shores of Indonesia, India, Sri Lanka and left a huge amount of mass, attributable loss of life not to set up the above-mentioned monitoring stations and early warning of such natural disasters.

Victims of the tsunami more than 155 thousand
