Destruction of Tokyo in the next 50 years?

Do you think an eartquake will destroy Tokyo in the next 50 years ?

The resaon for me making this thread is New Orleans. I watched some docus about the flooding of the New Orleans because of a hurricane. I always thought that something like this will never happen,......
I saw many docus about Tokyo,too. They said that the next big eartquake is not so far away.

What do you think?

I believe this would have a big impact on the world economy.>
