"... risk communication explains specifically what are the personal risks associated with risk area occupancy and also the hazard adjustments that can be taken to reduce hazard vulnerability."
This is the topic you're looking for.
I suggest you look for papers by Michael K. Lindell, Carla Prater, or Ronald W. Perry. These are the 3 authors of "Introduction to Emergency Management".

There is a PDF titled "Risk_Communication_MultiEthnic.PDF". This paper may be too theoretical, but their papers tend to bury specifics in the middle. Also, there is an extensive bibliography at the end. Hope this helps.
