Risk Overview
Liberty County carries a medium composite natural disaster risk, with a National Risk Index score of 83.0 out of 100 — placing it in the 83rd national percentile and near the national midpoint 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 hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at High risk — $51M in expected annual loss and about 0.31 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $1M in expected annual loss and about 69.72 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $396K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $68M in expected annual loss for a population of 65K.
Beyond physical exposure, Liberty County has a very low social vulnerability rating (how susceptible the population is to harm) and a low community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
History supports the rating: Liberty County has received 18 federal disaster declarations since 1977, including 9 for hurricane events and 3 for tropical storm events. The most recent was Hurricane Helene (hurricane), declared in September 2024.
Among 159 Georgia counties, Liberty County ranks #12 for overall natural disaster risk.
