US City Disaster Risk Rankings
The highest FEMA composite risk scores represented in our city directory, grouped by the county-equivalent area behind each score.
How this ranking works
Cities in the same FEMA area share the same hazard figures, so each area appears once. The list shows covered cities instead of counting one county score several times. Relative scores are comparison measures, not event probabilities.
