Double Whammy: Japan's Nightmare

Mar 13, 2011 By Arati Rao

In the afternoon of a working day, March 11, 2011, life changed for Japan.

The worst ever earthquake in Japanese history struck off the coast of the northeastern city of Sendai, on the island of Honshu.

The quake measured 8.9 on the Richter scale (a scale that measures earthquake intensity), powerful enough to shake buildings 400 km away in the capital city of Tokyo. But the nightmare was yet to come.

The nightmare from the sea

The earthquake happened out at sea and it triggered a tsunami.

Tsunami is a Japanese word meaning “harbor wave.” It is a body of water that is born near the epicenter of an earthquake. When it reaches land, this wall can be several meters high. In Japan's case, a 10-meter high wall raced towards the areas around Sendai.

The northeastern coastline of Japan was altered completely by the tsunami, as it swept inland taking everything – houses, cars, and boats – with it. More than the quake itself, the tsunami that followed has created untold damage. The full extent of Japanese loss is still unknown. Moreover, the tsunami and earthquake might have damaged nuclear reactors – and that is an ongoing story we are watching.

How is a tsunami formed?

Earthquakes, landslides, and volcanic activity – anything that displaces water, can cause a tsunami. Not all earthquakes generate tsunamis. First of all, it has to have its epicenter (the point where the earthquake actually happens) underwater. And even then, all underwater earthquakes do not result in tsunamis. This makes predicting tsunamis difficult.

The earth’s crust is full of “tectonic plates” on which continents sit and shift. When one tectonic plate butting up to the other moves and subducts (dives under the other plate) or pushes the other plate up, an earthquake is created.

If this happens underwater, the energy released by the movement of the earth's crust is transferred to the water. This could result in a wave. The wave is not very high at sea – but is very long. These waves have a lot of energy and can travel at almost 800 km per hour as they race towards land. When this “displaced water” reaches shallow coastal areas, the wall increases in height (all that water traveling from the deep ocean in a wave has to go somewhere). It slams onto land causing devastation and heavy flooding.

Tsunami warning: seek higher ground!

There are tsunami-warning stations all along the coast of Japan and throughout the Pacific Ocean.  These warnings allow people in low-lying areas to escape to higher ground if there is the threat of a tsunami. It is likely that a lot of people in Japan on March 11, did that. But the tsunami that came was very, very big and powerful and has still managed to cause a whole lot of damage and loss.

How can we help?

The Japanese Prime Minister has called it the worst crisis Japan has faced since WWII, and has asked for help. People and countries around the world are helping. Ask your school or local community how you can join efforts to help the tsunami victims in Japan.

This was very devastating. Something like this should be tried the very best not to be caused. I hope a lot of people found their loved ones, because I know how it feels . I just recently lost my grandpa . However it was very devastating . I didn't want to see him go. Imagine how many people got lost in this nightmare ! :'(

There was a tornado warning yesterday, and I was freaked out. The Japanese had to deal with a sudden wave of water obliterating their houses. Imagine how they felt.

Some news items say that the next place to be affected by an earthquake is California which is located at the fault line. When it is due, is an unknown fact, but it could happen anytime.

They said an earthquake would happen here (in the Bay Area) yesterday but it didn't so I'm happy... for now.

Japan has set up relief shelters for people to write their names and communicate with their missing loved ones, on paper. It's the best they can do for now. Our school is setting up a "1000 cranes" donation that we will send to Japan. If we buy a crane for 5 dollars, we can color it in, and write a message. I hope it will make a difference, and my heart goes out to them.

That's really cool. The leadership class in my school organizes these sorts of things and they're thinking of starting a project.

They are living on 5 liters a day which can last them for cooking and drinking, but not bathing. This was the case a few days ago.

I saw this on the news. There was this one aerial video of a sprawling town that was once packed full of residents, but now there are no buildings at all and NO PEOPLE. It's pretty serious, especially the radiation.

The earthquake wasn't that bad, if you factor in the distance.

First Haiti and now Japan but I hope that we can do something like give money to Japan. I know that people like celebrities and my school did something about Haiti we donated money to the red cross and I hope we can do the same.

Japan will need help quickly, after a series of natural and man-made disasters. The Japanese prime minister is right in saying this is the worst crisis from world war II.

Whenever an earthquake strikes anywhere in this world, one of the first to ever provide aid to that affected country is Japan. Likewise, all countries are trying to help Japan sort out this crisis. This shows that the when you help others, double that help is returned when you need it.

It's really bad! Earthquake, then tsunami, and then damaged nuclear reactors!

Did you know the earthquake moved Japan's coast 8 inches and shifted the Earth's axis about 2 inches???

Really?? I heard it was 8 feet.... not inches.. hmmmmm, I will have to look that up.

That is so terrible. At least Japan is a developed nation, so it can respond better, as opposed to somewhere like Haiti, which is a poorer country.

Yeah, that's true. Some other nations would have crumbled very early on.

That's really sad. :( I saw the tsunami on the news; it looked like a giant mud wave. I will ask my school to see what we are doing to help Japan.
