See book by Rebecca Solnit. A Paradise Built in Hell: The Extraordinary Communities that Arise in Disaster.I haven't read it so what do you guys think you got more of, a look at human nature or something more in what a crisis looks like?
Much solid info about many disasters in various lands. Summary: Generally all sorts of people step up and do what is needed. Much leadership and courage exercised by relative nobodies. After ordinary people get the worst taken care of, government entities arrive, destroy the spontaneous accomplishments and mechanisms of citizens so as to restablish their power and recreate the pattern of a citizenry dependent upon government. They also rewrite the narrative, downplaying or eliminating all accomplishments before their arrival and reestablish ment of "order" meaning actually their own power.
