Literally, the word tsunami comes from the Japanese tsu means harbor and nami meaning wave. Japan is one country that is often affected by the tsunami. Japanese history has recorded at least 195 tsunami occurred.
Many wrong perception about the tsunami. Most of the people think the same as the tsunami tidal waves. This perception is very popular given the appearance of a tsunami is like a high tide. Among researchers, this assumption is no longer fit the era.
Tsunamis occur causing interference originated from the displacement amounts of water, such as volcanic eruptions, earthquakes, landslides or meteorite that fell to earth. However, 90 percent of the tsunami originated from undersea earthquakes. History mentions only that caused the eruption of Mount Krakatau tsunami.
In the context of science, a vertical movement in the earth's crust, can lead to the ocean floor to rise or fall suddenly. This movement also causes the emergence of the energy flow of sea water. When they reached the shore, this energy flows into a large wave that resulted in a tsunami.
Tsunami wave velocity depends on the depth of the ocean where the waves occurs. Its speed can reach hundreds of kilometers per hour. When the tsunami reaches the coast, its speed will be about 50 km / h and its energy is very damaging coastal path. Mid-ocean tsunami wave heights of only a few centimeters to several meters. When it reaches the coast, wave height reaches maximum height.
As mentioned earlier, Japan is one of the countries that suffered most from the tsunami disaster. Besides Japan, there are a number of countries which had also felt the tsunami disaster in the history terdasyat. Here are the five biggest tsunami ever occurred:
A. 1883 Krakatau tsunami
The eruption of Mount Krakatau is terdasyat disaster in his day. At that time, Earth's weather cycles interrupted by longer periods of time. Eruption of Mount Krakatau presents a broad sea of lava. Eruption that plates which also caused a shift that led to the underwater tsunami. According to historical records, Karaktau tsunami extends to the south west coast of Africa and America. "The eruption of the shocks with the Earth's plates spread up the west coast of America, South Africa, and the strait which separates France and Britain," said George Pararas-Carayannis, Tsunami agrees.
2. 1498 Japanese Tsunami
Japan in 1498, shocked by the disaster which had never previously thought. An earthquake measuring 8.6 on the Richter scale which they usually feel a sudden tidal wave of Japanese society rewarded the settings for 17 yards. The death toll from tsunami waves that came to be called up to 31 thousand inhabitants.
3. 1755 Lisbon Tsunami
Lisboa bergeliat into the city center of trade. Disaster was coming, when an earthquake measuring 9 on the Richter scale shook the vast Atlantic ocean. As a result, tidal waves as high as 400 feet hit the Lisboa. 60 thousand people recorded killed in the disaster.
4. 1908 Tsunami Italy
The position of Italy right in the center of the Mediterranean plate makes the country vulnerable to earthquakes Pizza. Sure enough, in 1908, an earthquake shook Italy, located on the coast of Messina. As a result of the earthquake tsunami that killed 75 thousand people.
5. 2004 Indian Ocean Tsunami
Italy after the tsunami, the tsunami seemed to disappear. However, hundreds of citizens from some countries that are enclosed in the Indian Ocean screaming hysteria. Their homes by the tsunami terdashyat when entering the stage of modern human history. An earthquake measuring 9.3 on the Richter scale gave birth to the tsunami as high as 80 feet. Maldives, and Sri Lanka, Aceh is the region most affected by the tsunami. Hundreds of thousands of people become victims and the city's infrastructure was badly damaged.
5 Powerfull tsunami Throughout the history
The tsunami that struck the Mentawai, West Sumatra, some time ago leaving a deep sorrow. Still fresh in the memory of the tsunami that hit Aceh and surrounding areas in 2004. Disaster when it is so fierce. How many untold number of dead and damaged urban infrastructure.
Not surprisingly, when the earthquake rocked Aceh again, Wednesday, April 11, 2012 yesterday afternoon, panicked residents of Aceh. Moreover, the tsunami siren was also installed. They panic, scrambled out of the house and ran for higher ground. They fear, that diiukuti bersar earthquake aftershocks, some of it will be accompanied by a tsunami as it had been swept Aceh, 2004.
