Ever since I was a small child, I've loved disaster films, starting with Poseidon Adventure. If it was playing on the tv, I would come running in from the other room and beg my dad not to change the channel.

And a life-long love was born.

My rule for this list is it must be caused by a natural disaster, not supernatural or manmade (which took out many I would have liked to include, such as Jurassic Park or The Stand).
