if you look at the images provided in the link from your mail and select "View 
Details" then you can read the agreement that these images were specifically 
licensed to amnesty international for their press release. This means that we 
cannot use them.

I recall that such tagging schemes were applied for the typhoon mapping in the 
Philippines, see e.g. the instructions of http://tasks.hotosm.org/project/392, I 
am not sure if the damage tag has been approved as a general tagging style though.
