Risk Overview
Overall natural disaster risk in Liberty County is very low, with a National Risk Index score of 12.7 out of 100 — placing it in the 13th national percentile and among the lowest-risk counties in the country. 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 Medium risk — $2M in expected annual loss and about 0.26 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $493K in expected annual loss and about 85.69 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $140K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $5M in expected annual loss for a population of 6K.
Beyond physical exposure, Liberty County has a medium 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.
