What is disaster amnesia (also know as hazard amnesia)?
Essentially, it is the inability to contemplate or comprehend a similar disaster happening again.
NPR has a terrific article on how much lessons learned are unheeded and how unlikely disaster amnesia will improve.
Basically, all taxpayers should expect to continue to pay for the repeated mistakes of inhabiting in areas where disasters and other natural (and some manmade) hazards are very prone to happen, unless Rep. Ron Paul (R-Texas) has his way.
