I agree with Ugilick.
If the problem is that you aren't writing it, then you should make yourself write something. I can't tell you how many years I went where stories were in my head, but I was too lazy to write them. Once I started to posting in the forums that I was doing a certain thing and felt like people were expecting it to be finished, I actually started finishing them. If you make yourself work on it, no matter how long it takes, I promise you'll be glad that you finished it.
If you are having writer's block I'd suggest maybe doing a little research on natural disasters, conspiracy theories therein, ect. Find one or two main causes that you'd like to use as the reason for the disasters and stick too it. Don't over do yourself ;)
