Introduction:
A massive Tsunami (Japanese for “Harbor wave”) had hit southern Asia the day after Christmas 2004. The cause of the Tsunami was an offshore earthquake that results in the tectonic plates being displaced and the creation of a vertical shift in the ocean floor. This vertical shift lead to a large volume of water being uplifted and turned to create a huge wave that traveled up to 300 miles per hour, gradually slowing as it reached the shore. At that time, people in…show more content…

These countries had neither the proper disaster warning systems nor any type of acceptable emergency shelters. Additionally, they did not have an ample number of hospitals, medicines, supplies of food and enough shelters to care for the survivors of the tsunami. Therefore the wounded died suffering infections, hunger and depression and left thousands possibly missing. The tsunami washed parts of countries away leaving the inhabitants in total devastation. Though, the worst is yet to come. It has been found that people are now drinking from tainted water supplies, since the fact that many resources or cargoes were unable to reach the people in a timely manner. The need for clean water is pressing. Health officials say that cases of diarrhea illness were reported across the areas of South Asia. The World Health Organization predicated that about five million survivors of the calamity are at the risk of getting infections from the disease (Dr Samlee Plianbangchang, 2005). Volunteers attempting to treat the survivors are still struggling to provide the necessary help across all the nations affected. In addition to the diarrhea illnesses, there are major concerns about other illnesses such as cholera and typhoid. People can become infected very easily with the consumption of tainted food and water. Once infected, the individual can suffer form diarrhea, dehydration, and eventually death. Other illnesses

A tsunami is a series of fast moving waves in the ocean caused by powerful earthquakes or volcanic eruptions. A tsunami has a very long wavelength. It can be hundreds of kilometers long. Usually, a tsunami starts suddenly. The waves travel at a great speed across an ocean with little energy loss. They can remove sand from beaches, destroy trees, toss and drag vehicles, houses and even destroy whole towns. Tsunamis can even be by caused meteorite strikes, though it is very rare.

The water often draws back from the seacoast half of the wave period prior to the wave getting to the coast. If the slope of the coast is not deep, the water may pull back for hundreds of meters. People who do not know of the danger will often remain at the shore.

Tsunamis cannot be prevented. However, there are ways to help stop people dying from a tsunami. International and regional warning systems, especially for the Pacific Ocean, issue alerts before the big waves reach the shore. Because an earthquake that caused the tsunami can be felt before the wave gets to the shore, people can be warned to go somewhere safe.

The deadliest tsunami recorded was on 26 December 2004. It was caused by an earthquake. The earthquake was said to have a magnitude of 9.3 on the Moment magnitude scale. It was centered in the ocean near the coast of Sumatra, Indonesia. Over 215,000 people, mainly on the shores of the Indian Ocean, died from this disaster. The giant wave moved very quickly. Hundreds of thousands of people in Indonesia, Sri Lanka, Thailand, India, Somalia, and other nations, were killed or injured by it.

Tsunamis are often called tidal waves because they usually rise and fall more slowly than ordinary ocean surface waves. This name is misleading, because tsunamis are not related to tides; they merely rise slowly like tides do, though less slowly.

Tsunami is a Japanese word for Harbor Wave'. (Tsu = Harbor' + Nami = Wave).
