I feel compelled to point out that here we are well into a really, really bad situation with the destruction of core infrastructure, urban power failures, tens of thousands of people unable to go home, gas shortages...and based on the chitter-chatter I've read n the past (here and elsewhere) - we should be well into zombie apocalypse territory by now. It's not happening that way. People are helping. the vast majority of people are banding together and helping solve the problems as best they can. There are no roving bands of armed mercenaries. There are no riots. There are some fights over gas - yes, I see that too. And order is being maintained.
I prefer to plan for reality, not a Mad Max fantasy.
While I didn't pontificate any doom here or elsewhere, I think this thread needs a counter-point. :-)
First, I'm unsurprised that things were orderly and that I think that serious social disorder is not a likely outcome of a natural disaster all things being equal. But I'm not sure why you seem to suggest we can draw a sweeping generalization based on this latest event.
Clearly riots / serious social disorder does occur. The LA riots showed us this can happen, even in modern America. If something can happen, it likely will happen again at some point. Perhaps not commonly, but the same can be said up here in the for a large earthquake, tornado, for your house burning down, your car getting stuck in a snowstorm, a chemical spill, your car crashing, whatever.
Personally, I think in a short term natural disaster, people are likely to work together for the most part. I don't see a large correlation between natural disasters and social unrest.
That said, social unrest is just another infrequent, but possible risk and I'm not sure why we'd hold it up and suggest it is less worth being prepared for than a chemical spill or some other infrequent risk and why you think people who might consider it in their preparations have jumped the shark more than for preparing for some other low risk event.
