Tsunami in Japan: nature – that terrible power
They say that beauty is a terrible force. But if we leave aside the colorful turns of phrase, and return to reality, we have to admit that the most terrible power of this element, the existence of the forces of nature. Mankind often forgets about it – and then come to him reminders in the form of such tragedies as the tsunami in Japan on 11 March 2011, however, the waves of this tsunami were not the highest registered in the history of the tsunami.
Comparable in strength to the magnitude 9 earthquake and ensuing tsunami with a height of 5 meters according to scientists has already taken place in Japan in 1700. Interestingly, the Japanese began to document tsunami in the early 16th century.
The tsunami waves swept the entire Pacific basin (coast of the U.S., Canada, Mexico, Chile), but in other countries the tsunami has already lost his strength and looked at worst like waves of several meters height. Height struck Japan waves averaged about ten meters and it took them about 20 minutes after the start of earthquake to reach the shore. In some cases were marked by waves of up to forty meters.
The scale of the destruction and victims caused by the tsunami was huge in the first place for the reason that the coast of Japan is one of the most densely populated in the world. Japanese mountainous Islands are spacious enough valley for the location of large cities mainly on the coast. The result was about 400 destroyed thousands of buildings, killed about 19 thousand people (more than 3 thousand of them are missing).
Japanese nuclear nightmare
Messages about the earthquake and tsunami in Japan shocked the whole world, however in suspense the entire planet news the crash site was kept in suspense for several weeks due to the accident at the nuclear power plant “Fukushima-1”. Emergency situations of various degrees of complexity have arisen at several Japanese nuclear power plants, and in the vicinity observed a transient increase of the radiation background at the NPP “Fukushima-2” killed one of the employees. But the true test is “Japanese Chernobyl”, was an emergency situation at the station “Fukushima-1”.
Tremors and the subsequent impact of tsunami waves Tsunami: wave of the killer station, located on the shore of the sea, led to the failure of the external power supply system. In this case there was a mode by using backup diesel generators, but the working design of the NPP and the control characteristics of the equipment were not ready for such power earthquake and ensuing tsunami. As a result out of order, all systems normal and emergency cooling, the reactors were automatically turned off and stops working completely.
Material damage from the earthquake and the subsequent tsunami has amounted to 300 billion dollars. More than 16 thousand people were killed. Was displaced more than 5 million tons of waste, with 1.5 million took to the open ocean
