Here is a link to the 2012 edition of the UK’s National Risk Register of Civil Emergencies. Thanks to John Twigg for calling this to my attention.
Although the U.S. has done a national risk assessment, the final document was classified. I did find an unclassified version of the results, on the DHS website. A copy of the 7- page unclassified version of the Strategic National Risk Assessment (dated Dec. 2011) is posted here. If anyone knows of additional information in the public domain on this topic, please let me know.
It would be interesting to compare the approaches and results of both studies.
