TSUNAMI DISASTER


A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, some volcanic eruptions and other underwater explosions, landslides, underwater earthquakes, large asteroid impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can be devastating due to the immense volumes of water and energy involved. Since meteorites are small, they will not generate a tsunami.It is not known what caused the Storegga sediments to fail. It may have been due to overloading of the sediments causing them to become unstable and they then failed solely as a result of being overloaded. It is also possible that an earthquake caused the sediments to become unstable and then fail. Another theory is that a release of gas hydrates (methane etc.,) caused the slump.

tsunami is a big natural disaster and can cause a lost in life and materials. once it attack, there's only a small chance for human to survive. tsunami had attack Malaysia once in 2004. it cause a great lost. many people suffer and died. the survivor need a lot of support to continue their life. during that time, many individuals, government and non-government organization and companies give a hand on them. only after the disaster the government take a precaution step to detect the tsunami before it attack.
