its not that the tragedy will not occur, i have read a few reports that the west coast of the US is due an earthquake, but that in richer countries they have a resources to develop and maintain early warning systems. their infrastructure is better designed to withstand natures forces as they can afford it. we all live in areas of the world that can be hit by a natural disaster, there are no exclusions to this rule.

>From this point, no tragedy will occur with U.S. or any 1st. world country?? On any country placed between those earth's boards named tectronic (or something, I'm not sure for the name) can occur exactly the same.. And zilions, bilions (or just one who knows) of people will die.. There is no protection for this !
