Risk Overview
FEMA's National Risk Index rates Maury County at low composite risk, with a National Risk Index score of 79.3 out of 100 — placing it in the 79th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in tornado (violently rotating columns of air capable of catastrophic local damage) at High risk — $12M in expected annual loss and about 0.55 events per year; strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $3M in expected annual loss and about 6.22 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $6M in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $46M in expected annual loss for a population of 101K.
Beyond physical exposure, Maury County has a low social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Maury County has received 21 federal disaster declarations since 1973, including 12 for severe storm events and 3 for winter storm events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 95 Tennessee counties, Maury County ranks #16 for overall natural disaster risk.
