A Small Rant (off topic from tech) Earthquake in America

Over the years I've seen all the Earthquake's hit in various parts of the world and I've been thinking why has America been spared (so far) from the major devastating quakes ?

Answer: I don't know

But it seems that the quakes have been getting stronger and more intense in there happenings. I can only think that it's a matter of time before a major destructive earthquake like the one that hit Japan almost a year ago (3/11/2011) will hit American shores or soil soon.

The thought that every day the big quake waits to happen the stronger it will be in magnitude seems to stick with me almost constantly. I'm not making predictions I'm only stating my opinion.

One major concern for me is the New Madrid Seismic Zone since I live relatively close to the fault I figure it's best to be prepared as much as possible just in case anyway.

Back when the 5.9 earthquake hit Virginia and feeling it rattle nearly the entire eastern have of the US got me thinking what would happen if it was larger, like around 9.0 magnitude or larger earthquake?

How much would be left to recover?

How long would it take rescue workers to get to the areas? (There would be a lot)

What kind of shape would the Government be in and how would it affect aid?    

So for me all it's done is leave me with questions of which I have no answer other than to take care of myself and others where I can.

Have a supply of basic needed supplies in-case a disaster of some kind hits like extra non perishable foods. like freeze dried items that can last up to 25 years if stored properly and plenty of water at lest 1 gallon per freeze dried can of food and a gallon of water per person per day for ever how long you think you need.

A first aid kit in a grab and go bag with essential items that is ready at all times in case you need to get out of town quickly. May ad more later but this is just a start to being a prepared as you can for you and your families survival.
