Risk Overview
Overall natural disaster risk in Henry County is low, with a National Risk Index score of 44.8 out of 100 — placing it in the 45th 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 Medium risk — $4M in expected annual loss and about 0.31 events per year; earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $718K in expected annual loss and about 0.00 events per year; and hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $451K in expected annual loss and about 4.58 events per year. Across all hazards, FEMA estimates $15M in expected annual loss for a population of 49K.
Beyond physical exposure, Henry 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.
History supports the rating: Henry County has received 18 federal disaster declarations since 1974, including 6 for severe storm events and 4 for snowstorm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 92 Indiana counties, Henry County ranks #41 for overall natural disaster risk.
