Have you heard if there is going to be a casualty list anytime soon. Or is there a place that missing persons can be located. On 911 there were locations to post missing persons info.
Sorry to say that they probably can't even get to most of the casualties for days yet. To put it brutally, identification of bodies after that much time will be difficult. It's going to take a long time.
For the living, I suspect that the Red Cross and other organizations will have check-in points, and you can look there.
