The plan? YOU WILL BE ON YOUR OWN FOR AT LEAST 3 DAYS MAYBE MORE. there is no way to set up a disaster pan that will cover that period. You can’t predict exactly where and when the disaster will occur. So you can’t preposition relief supplies personnel etc. the initial period will be figuring out what’s needed, where its needed and how you are going to get it there.
That’s what I mean. The plan could be Prepare our citizens what to expect. This is ongoing, not just at time of the disaster. Immediately, have the national guard with helicopters and navy (if disaster is on a coastline) ready to provide medical services, food, water, emergency supplies as needed. At this point my brain power is out of ideas, so someone else can take over. But you get the idea. I do think that each community can imagine what might happen and how to deal with it ie no gas, no power, etc. Mainly cut the red tape, get govt out of way. Provide way for citizens to communicate ie have phone stations. Maybe a think tank could come up with ideas. Thinking, planning and putting on paper is better than nothing. Maybe not, it might make people feel more victimized.
