NATURAL DISASTER

NATURAL DISASTER
TSUNAMI
INTRODUCE It is a complex event involving a group of high-energy waves and resizable that occur when an extraordinary phenomenon vertically displaces a large water mass.This type of waves remove an amount much higher than the surface waves caused by wind water. It is estimated that 90% of these phenomena are caused by earthquakes, in which case they receive the mostcorrect and accurate name of "tectonic tidal waves."
Term Most tsunamis are caused by earthquakes of great magnitude under the water surface. For a tsunami originates the seabed should be moved abruptlyvertically, so that a great mass of ocean water is pushed outside its normal balance. When this mass of water tries to regain its balance generates waves. The size of the tsunami will be determinedby the magnitude of the vertical deformation of seafloor among other parameters such as the depth of the seabed. Not all earthquakes under the water surface generate tidal waves, but only those ofconsiderable magnitude with hypocenter at the point of adequate depth.
JAPAN On March 11, 2011 an earthquake measuring 9.0 on the Richter scale hit Japan.
After the earthquake a tsunami warning (tsunami)to the Pacific coast of Japan and other countries, including New Zealand, Australia, Russia, Guam, the Philippines, Indonesia, Papua New Guinea, Nauru, Hawaii, Northern Mariana Islands, Unitedgenerated States, Taiwan, Central America, Mexico and the coasts of South America, particularly Colombia, Ecuador, Peru and Chile.28 the tsunami warning issued by Japan was the most serious in its localalert, which means that He expected a wave of 10 meters.
