BIG EARTHQUAKES??

I read an interesting article which was in TIME online,
and that was about the places that can have big earthquakes in the future.
They introduced 5 of them, including Los Angels, Tokyo, Tehran (Iran), Pacific Northwest,
and Indonesia. Above all, Sumatra (Indonesia) just had an 7.6 earthquake last month, killed more than 1000 people.
As for Tokyo, one of the busiest city in the world, it is estimated that at least 10000 people
will be killed and $1 trillion damages will be caused if the big earthquakes like in 1923 hits the city. The 1923 earthquake in Tokyo killed 150000 citizens.
Although Okinawa have had few earthquakes which are considered big in the past,
I think we have to be prepared for the earthquakes at least, such as connecting shelves to the wall, and storing food and bottles of water.
By the way, there is a company that makes houses, and they invented an air cushion
that prevent houses from being damaged by earthquakes. That was pretty interesting.
