Arive of 30m(100ft) high Wave in Kesennuma | Tsunami Japan 2011

Although the

2011

tsunami

devastated more than 600 kilometers of the east coast of Japan, one area was especially affected by the

tsunami

and the damage to life and property was completely surpassed in scope and horror. This area is roughly bounded by the port city of Onagawa, where the tsunami occurred. A truly impressive force continues through the city of Minamisanriku, which we talked about in the previous part, then passes through the city of Kesanuma and ends in Rikuzantakata, which literally disappeared from the world map further north. The damage after the tsunami was also enormous, although visibly a little weaker.

In this episode we take a closer look at the city of Kasanuma and explain why the city was so devastated and was one of the four cities most affected by this catastrophe. Friends, welcome to the top topics channel. This video is part of a series dedicated to the tenth anniversary of the

2011

Tohoku earthquake and tsunami. The first and fundamental reason why the city of Casanova, as well as the entire area, was severely affected is the location of the city, the The city is located right in front of the epicenter of the earthquake where energy was released.

In the tectonic fold and the seabed was raised this fact and the distance of the city only 65 miles from the epicenter was enough indication that the tsunami would hit the city with great force. and very quickly. Another reason is that the entire northern area of ​​Miyagi Prefecture, where the city is located, has sunk slightly into the Earth's crust up to three-quarters of a meter, which has significantly facilitated the spread of the tsunami. If we look closely at the structure of the coast, one might think that the city was well protected by deep water. bay in which it is located and also by the island of Oshima, but as is well known, it is in the deep bay where the effects of the tsunami are greatly enhanced since the tsunami coming from the open sea is pushed towards a narrow space where it begins to accumulate a large amount of energy in the

wave

that would otherwise overflow plus the overall duration of the tsunami is significantly prolonged the

wave

manifests itself as a flood of furiously flowing and rapidly rising water the city of kesanuma was damaged by the existence of the island of oshima when a strong current was pushed towards this base of the tsunami and just before the city merged into a single current that invaded the city like when two great huge and flooded rivers come together, the waves spread along the path of least resistance At first, in the local port the situation did not seem dangerous and the river and the deep bay were able to absorb the first waves of water, however, the flow of water continued to grow and, furthermore, after the flooding of the port, the water had nowhere to spread.

This narrow discharge worked like a plug and the entire mass of water immediately began to spread across this peninsula towards the center of the city then something happened that was fatal for the city of Kasanuma as well as for the city of Minamisandriku in Agava and Rikuzentakata. The wave has long been speculated because it was so large that it broke well before the coast and witnesses described it in the affected cities only as a sudden increase in the flow of water and the rising water level recently however A unique video has been released from the town of Casanuma where this enormous wall of water was captured.

What you are about to see is a wave of destruction that was located only for this area and that, according to scientists at the University of Tokyo, comes from a different source than the wave that hit the entire coast of Japan. The investigation continues, but we know that this was just another reason why the area was so damaged as the waves generated fire in front of the shore and it flowed towards the city in the form of a furious flood, the water immediately flowed through the peninsula merging with the current of the Okava River creating a terrifying spectacle in a matter of minutes, the city center was completely devastated and the tsunami showed its incredibly destructive power.

The entire destruction of the city was completed by a large fire that broke out in the oil product refineries, of which there were several in the city. It was one of the most devastating fires in Japanese history. The next day, only rubble of the city remained. The toll was terrifying: almost 1,500 dead and billions of dollars in damage, as you can see, the renewal of the city still continues today, especially in the peninsula area. Recovery will take many more years, but progress is still visible after 10 years. The elevation of the space is artificially increased like in other cities so that any additional waves won't cause as much damage.
