Excellent, thanks !
Here is some quick analysis :
Building :
http://tagstat.hypercube.telascience.org/haiti/tagdetails.php?tag=building
tag uses node way
yes 951 4 947
collapsed 431 314 117
tank 27 0 27
risky 2 2 0
Risky is surprisingly rare considering its usefulness, but I guess that
with satellite imagery it is only possible to distinguish between normal
and collapsed.
Other relevant tags :

http://tagstat.hypercube.telascience.org/haiti/tagdetails.php?tag=tourism
tag value uses node way
refugee yes 90 2 88
tourism camp_site 86 3 83
There is only one "amenity:camp"... And it is in Copenhagen !
Note the interesting "residential:shantytown" area tag that might be
useful to distinguish areas of different building types.
http://tagstat.hypercube.telascience.org/haiti/search.php?query=earthquake
does not show many "earthquake:*" tags. What we have :
