Without informa…Every year, a lot of people are killed from natural disasters, such as earthquakes, flood, and volcano of these, one of the must devastating is the tsunami. A tsunami is a series of huge waves in ocean. It has various causes, but the most common one is an earthquake. It has a large volume of water and it moves very fast, and the wave can swallow everything in its path.
When there is a large earthquake, a wave can be generated by the sudden movement of the plate. The initial wave is still small, but it has very long wave length. People near this point can’t notice it. However when it approaches land, the depth becomes shallow, and the wave becomes huge. When it is hits the land coast, 2 or 3 kilometers inland can be submerged. Usually the wave surges two or more times, and 2nd or the 3rd wave tends to be the biggest.
There was a huge Tsunami on December 26, 2004, in surrounding Sumatra. The size of the earthquake had a magnitude of 9.3, and the wave was as high as 34m. The wave’s initial speed was about 700km/h, which is the same as a jet plane. There were 229,866 casualties, and it destroyed almost everything in affected areas. People lost their home, family, and friends. Furthermore water supply, electricity, and institution were damaged or destroyed severely affecting the economy and infrastructure. Support of two billion dollars (about 205 billion yen) in total was given from around the world. Volunteers came from all over the world to the affected countries, and gave counseling and help to the victims. The entire world helped but there is still a long way to go. About two years have passed since the wave struck, but in some parts the prospect of the revival is not good.

If you live in affected areas, you should prepare in advance to protect by your self. You have to know where there is a safe place near you. Before an earthquake, you should prepare water, food and radio. Radio is important to get information about the wave as much as possible. If you feel an earthquake, turn on your radio or TV to get information about the wave and run away to high place immediately.
Forces of nature can’t be stopped, but we can reduce loss of life. Citizens can take above the steps to be help. Government must attempt to protect vulnerable areas from the waves. They can plant trees in coast all areas. Governments should educate the population through teaching children in schools and news information. International cooperation is needed to send warning information immediately, when a tsunami or earthquake happens, and to help after wards. Through these methods, we can reduce loss of life.
