Is it dodgy to send zakah to disaster victims?

Yesterday, an akhwat said that after she asked around, she got the impression that it is better to send infaq or shadaqah to disaster victims rather than zakah, because it is feared that the organiser cannot distinguish between the rightful recipients or not.

Well, although I can understand the viewpoint, but I think it's a bit dodgy. My logic (of course I shouldn't use logics in fiqih, but hey, I'm not an expert) is that if an ibnu sabil (a wayfarer who's got trouble in accessing his means, eventhough he is actually rich) is a rightful recipient of zakah (muzakki), why can't disaster victims, whose properties and asset are clearly ripped off of them, should be questioned whether they are muzakki or not?

Clearly, I need to find out...
