The ratings, number 1 being the riskiest, are fascinating in that they also include the increase of risk (when available) based on how the USGS data changed from 1989 to 2008.

*report shows long term leak at New York plant*
The reactor with the highest risk rating for earthquake damage in the country is a mere 24 miles north of New York City, the country’s most populous metropolitan area.
With a chance of a core damage from a quake estimated at 1 in 10,000 each year,
under NRC guidelines, that’s right on the verge of requiring “immediate concern regarding adequate protection” of the public.
The two reactors at Indian Point generate up to 30% of the electricity for NYC.
It will be interesting to see, given the new risk assessments, how the future of Indian Point and the rest of the risky bunch pans out....
