I have a project on preparedness for disaster

Answer 1

Are you talking about individual, family organizational, community or governmental preparedness?

Since this is not my area of expertise, I searched Google under the key words "disaster preparation" to get these possible sources:

http://www.ready.gov/
http://www.redcross.org/services/disaster/0,1082,0_500_,00.html
http://www.nodoom.com/
http://www.fema.gov/areyouready/
http://www.nlm.nih.gov/medlineplus/disasterpreparationandrecovery.html

There are many other sites available. In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
