So We Had An Earthquake Last Night

I wake up to the local news and people talking about feeling the earthquake (shows how sound of a sleeper I am). It was a 5.2 centered in southern Illinois. It also got me thinking what would have happened if this quake was a little larger (say a 6 or 7), especially in an area not built to withstand such phenomenons of nature. I wonder how well our government would respond, and how well things would be handled financially. That could be enough to really throw our country into bankruptcy.
