It would make sense, but if you pick up a cellphone in an emergency state like a natural disaster of this magnitude (no pun intended), you may find that any number you dial is greeted with a message telling you that all lines are busy to non-emergency crew traffic, and to please try your call again later (Ask anyone along the Eastern Seaboard or Gulf Coast of the US about this right after a hurricane, for example).
Even your calls to 112, 118, 119, 000, 911, etc. would run into this if the towers are that congested.
Meanwhile, there might still be a little bandwidth left from that tower for someone using a cellphone to send a few packets, hoping that someone can save them. Just wildly guessing that people are more likely to pick up the phone and call for help, or try to call family, or receive calls from family after said disaster, and guessing that data would run on a different channel of sorts for cell networks, I'd safely guess that getting to the Facebook or Twitter pages (barring any Fail Whales) would be easier than calling someone.
If your wall or tweet happens to reach someone who has access to the emergency crew channels for a given disaster, then it might be an effective option to go this route, if you have no other viable option.
It beats dying, if you have something to live for.
That's just my two cents, though.
