The nuclear plants problems

A wave of 15 metres hit the nuclear power plant of fukushima daiichi.

When the eartquake happened, every nuclear power reactos tripped as designed and the nuclear fission process was stopped. But the problem is that that the fuel in a nuclear reactor continues to produce considerable amounts of heat even when fission has stopped.
Normaly, a circulating water continue to work even if the reactor has stopped in order to cool it down but in the fukushima daiichi nuclear power plants, the 1 to 3 reactors has lost the pumps that provided this cooling water. Fukushima Daiichi was designed to support a 6 metres wave but 15 metres was too much.

It is not clear how many people are still living in the evacuation zone, but reports said police had counted at least 60 families.

After the disaster the government also declared a wider 10km zone around the 20km evacuation area where people should either stay indoors or leave.

A radioactive cloud was spread from the central plant in all the world, it’s a chance for Japan that the wind comes from the continent and goes to the ocean. Because of that, Japan didn’t incure the cloud which, from most of its part, vanished in the ocean. Here is and animation of the Radioactive cloud :

Spread of Radioactive Cloud from Fukushima-Animated Prediction..

But in order to cool down the dammages reactors, the autorities used the ocean seas. That commited a big polution with consequences in the future that noone can predict.

The tsunami

The enormous earthquake caused, one of the biggest tsunami the Japan as ever seen.

The tsunami, was created far from the Sendai coasts and rolled across the Pacific at 800km/h – as fast as a jetliner – before hitting Hawaii and the US West Coast, but there were no reports of major damage from those regions.

As soon as the earthquake hits the Japanese coasts, Tsunamis alerts were done in all the cities that could be wounded by the tsunami. The alert were made by city speakers, on every tv channels and on every radios but no one could expect the speed and the strength of the wave and many people were surprised by it.

Strong waves hit Japan’s Miyagi and Fukushima prefectures, damaging dozens of coastal communities.

A 10m wave struck Sendai, deluging farmland and sweeping cars across the airport’s runway. Fires broke out in the centre of the city.

On that web site, you can see satellite photos from Japan, before and after the Tsunami :

The earth quake

On 11 march of May, Japan was rocked by alarge earthquake close from the Sendai coast.

The reports put the epicentre of the quake in the Pacific Ocean about 66km east of Sendai, at 330km north northeast of Tokyo, at a depth of between 26 and 40km. The magnitude on the richter scale is estimated at 9.

The quake hits at 11.32pm local time. It have caused power failures in large parts of northern Honshu and severely shaken buildings.

In order to compare the scale of that earth quake, we can compare it to the earthquake of Haiti which was “only” at 7 on the richter scale and caused the death of more than 150 000 people and many bilions of dollars.
The power of that quake shift the axis of earth of 6.5 inches. The temblor also modify the Earth rotation and shorts the day by about 1.8 microseconds.

The earth quake didn’t cause so many damage by itself, at that moment, we can just notice minor injuries from falls or falling household effects were beginning to filter through on local media.
Miyagi Prefecture police reported no major damage or casualties as of 11.55pm Japan time.
At that moment, every train, every nuclear plants and many other things of the country automaticaly stoped by themselves for security purposes.
Parts of Sendai, a city of about one million people, lost power and there were also reports of blackouts in Fukushima and Yamagata.

Some people said that it was the most powerful earthquake of all the Japanese history.

The quake was the fifth-largest in the world since 1900 and nearly 8,000 times stronger than the one which devastated Christchurch, New Zealand, last month, said scientists.

That earthquake caused a big tsunami on the japaneses coasts.

How the Japanese people try to prepare themselves to natural disasters

The Japanese people is one of the most prepared people to the natural disasters.

The entire Japanese history is made of earthquake, tsunamis (which is a Japanese name the signified “the port wave”), volcano and typhoon. For that reason, there is not so many old buildings in Japan.

From the earlier education in Japan, everybody learn to children how to do if a natural catastrophe happens.

There is exercises which learn to everybody the simple things to do to protect itself during an earthquake, you have to turn of the house gas, to open the door and hide under a desk or a table for example. Each time an earthquake happen, television channel shows the intensity and gives the instruction if a tsunami comes.

The rivers sides are made to deal with the day of rain that occures during the thypoon in august.

For the tsunami, there is special roads with arrows to show to people the most direct way to go in the mountain and be safe.

Alone on an island

 

Let me take a break in the consistency of my blog to introduce some

part of myself.

I would like to present you some songs or books I would take with me on

a desert island (like in the BBC program “Desert Island Discs”).

Here is my 8 songs :

  • Summer – Joe Hisaishi : It’s not a song but just a music. It’s the ost

of the japanese film “Kikujiro’s summer” which is one of my favorite

film.

  • La Marseillaise – Rouget de Lisle : It’s a song that keep strength for

people who listen it. It’s a music that symbolyse that if we fight, we

can be better.

  • The OST of Star Wars : It’s a great OST, composed by John William and

played by the Orchestra of London. It’s musics I really love.

  • Emmenez moi – Aznavour : I would take this song because in the lyrics

it says that misery is better under the sun.

  • Yesterday – Beatles : This song talk about life and the time which goes

and transform you step by step.

  • It’s a hard life – Queen : It’s a song that remind me when I was in

college and when I discovered the music of Queen.

  • Crazy train – Ozzy Osbourne : Crazy train is one of my favorite song

when I play the game “guitar hero”. On the desert island I will play

“Air Guitar Hero” with crazy train in my ears.

  • Sinsei no merigorando – Joe Hisaishi : this music is the OST of the

animated film “the howl moving castle”, its a waltz on the theme “the

merry-go-round of life” which gives me the envy to danse.

The book I would bring :

  • The Complete Book of Survival : Because entertainment is fun but on a

desert island, I fisrt have to survive.

The luxury item I would bring :

  • A botle of a very good wine : A very good wine can make you feel better and forget your problemes for a while.

Second step : Rising the future queen to have the first litter

Once you have your future queen, put it into a test tube with water and some cotton. Clog the test tube and let it in a drawer for a month with no food and no light.

If the queen need to eat, it will spawn some sterile eggs to eat them after.

After a month, watch at the test tube. If there is no new ants inside, it’s certainly because the ant you captured was not milt.

the geological situation around Japan

Japan is a country made of several islands, those islands are primarily the result of several large oceanic movements. It has been made during over hundreds of millions of years. It’s the result of the subduction of the Philippine, Amurian, Pacific, Okhotsk and Okinawa Plates.

Originally, Japan was attached to the eastern coast of the Eurasian continent.

Japan is situated on the Pacific Ring of Fire which is a very famous volcanic zone. That situation explain the many earthquakes and the big volcanic activity that happen in Japan.

Because of the subduction of the plates, scientists say that Japan will disappeared in the future sinking under the pacific ocean.
