I found a link to a report from back in 1989 that was put together for FEMA. I haven't read much of it yet, but what I have, while rather dry, does give a multi level insite into various scenarios. I would be interested in a discussion if anyone has time to read much of this. Particularly into how this has changed in the years since then.

Here is the link.
