Somes Causes of Tsunami

Tsunamis are a frequent seismic waves caused by earthquakes as the tectonic plates beneath the ocean floor collide. This is sometimes not an earthquake tsunami itself, but may be in order to run it, as a result of sea landslides caused by the initial earthquake. This led to mass erosion surface of the water in the lines that often get better as a result of training in large waves in shallow coastal line of bad hike. The third cause tsunamis is volcanic eruption. 

Earthquakes marine

Oceanic earthquakes far the most common cause of tsunamis. The reason is that the tectonic plates beneath the surface. They are located under the seabed sometimes rub or collide with each other, which causes a lot of energy to expel. It's heat and energy caused by water as a result of the pressure exerted from the bottom up. To make it clearer what actually happens during an earthquake in the sea is that the heavy tectonic plate trying to make its way through the push. Tectonic plates under the lighter plate is always to condensed matter such as stones, which runs along the asthenosphere version, partially skinned weaker than the Earth's mantle. Plate tectonics also called litospheric plates moving together is known about the asthenosphere.Tsunami occurs because, while the heavy plate trying to slide under the lighter, may end up stuck pushing pressure that leads between the two plates as the weight of the construction. Mild lateral plate and down What happens then is that the light reaches its limit plate is pulled down, suddenly snaps back to the original surface, which causes the pressure exploded upward. This pressure forced the water up, which forms a humongous shaft. 

The Ring of Fire 

Tsunamis can be so powerful that they can travel thousands of miles just beyond the banks to crash. Most tsunamis occur in the Pacific Ocean is the largest body of water on Earth. It covers rd 1/3 of the earth's surface and is surrounded by deep ocean trenches, island arcs and mountain landscape. Therefore, this area is often called the "Ring of Fire" because it is vulnerable to earthquakes.With about 2/3 rd of the sea world, the consequences of strong earthquakes oceans have been a disaster. An example of the impact of the tsunami, the Christmas tsunami that struck the Indian Ocean in 2004. The fact is that the earthquake occurred on the island of Sumatra, and the magnitude of the earthquake was 9.2 on the Richter scale. The earthquake caused a series of tsunamis that swept across Indonesia, India, Madagascar and Ethiopia! This tsunami was the worst, she claimed the lives of more than 283,000, and completely destroyed the landscape, buildings and all things related.Hopefully, now you know more about tsunamis and why they took place. Other possibilities, such as a tsunami can be created Due meteoric impact and artificial phenomena such as nuclear weapons test underwater in the sea. Scientists have not come up with a way to prevent a tsunami if certain steps are taken to allow us, as if approaching tsunami through the identification of a specific set of satellite fields and read waves predict.

Earthquake and Tsunami Devastate Japan

Several reports of Japanese media quoted as saying that a ship with a hundred people and a train with an unknown number of passengers disappeared too. The tidal waves that accompanied Tsunami were reported to be as large as 33 feet destroy anything that has in its own way. This mass destruction were memories of the 2004 tsunami in Asia and brought warnings in Australia, the Philippines, Taiwan, Indonesia and New Zealand. In regions of the Pacific, including areas as far away as South America, the U.S. West Coast, Canada and Alaska, high alarm in the wake of the tsunami warning triggered by an earthquake were released."The earthquake has caused major damage in broad areas in northern Japan," Prime Minister Naoto Kan said was quoted in a press conference. Thousands of people from various regions around nuclear power plants, reported problems were due to the earthquake were evacuated. According to the Japanese Prime Minister, close all nuclear power plants safely and without radiation leak areas, as reported by the deadly earthquake.The disaster has left most of the dark places in Tokyo as nuclear power plants were automatically shut down due to the earthquake. Sections in Kesennuma, Miyagi, a city of nearly 70,000 people lived, the situation has worsened throughout the night by the fire that broke out after the tsunami knocked several vehicles causing oil and gas to escape.Although Japan has faced several earthquakes in its history, it has been reported to be destructive. The extent of the damage has not yet been officially reported, but the quake was horrific scale as the tsunami waves penetrated several miles inland before they withdrew. Video of water walls enchanting everything in their way and the uncontrollable fire broke out in several areas, as has been recognized by various news channels Japanese media to come, no less than the disasters that appears in Hollywood movies . The man who was beaten in the office or on the road told the media on foot, even on the roads was similar across the deck of a ship on the high seas. Of course it is impossible to pin down the large-scale destruction that this earthquake caused the nation. Hundreds of people were killed and many deaths were not officially reported.In the past, Japan has one of the deadliest earthquakes in the 20th century on 1 September 1923 has seen. Known as the Great Kanto Earthquake hit this earthquake, the Kanto plain. Destroy Tokyo and Yokohama different parts of almost 1,40,000 people had in this worst earthquake measured 7.9 on the Richter scale is finally dead. Although the Japan earthquake on March 11 is the most affected of the story, we can only pray the losses are minimal.U.S. President Barack Obama and the head of the United Nations, Ban Ki-moon to send condolences to the victims and their families. The United Nations, European Union, United States and China in the foreground, to get aid to the victims of the earthquake. In fact, all the major governments of the world are ready to help Japan in this time of loss and grief. We come to the people in Japan to help in these difficult times.Governments need some other countries also include a wide availability of the Japanese disaster. Japan has set the gold standard for themselves when it comes to planning. Almost the entire population is religiously cope with tips and strategies of other emergencies trained. The public infrastructure is developed in such a way that natural disasters can cause a minimal loss. For example, although some nuclear reactors have had problems encountered during the earthquake, were effectively managed and radiation leaks have been reported.

Similarly, there are no words to describe the ability of Japanese architects and engineers whose efforts are Japan, one of the best economies in the world. We have seen many countries in the past reduced to rubble, and even an earthquake measuring between 7 and 7.5. E 'only Japan that was able to withstand a strong earthquake. I do not deny the fact that the loss due to the earthquake (as we shall see in the media) is certainly the largest, but some important lessons to be learned in this time of crisis in Japan. Emergency preparedness, and effective management of disasters are some lessons we can learn from the Japanese people, not to mention the quality of hard work and never say die spirit, for which he was famous, because for centuries. Japan certainly recover from losses over time, as it has done in the past natural disasters, although it may take some time, as has been the large-scale destruction.As Japan struggles with the biggest natural disaster in its history, we pray for the victims and families who have lost their lives. Almighty grant each of us the wisdom and strength to the proof of these circumstances are difficult.
