Risk Overview

Overall natural disaster risk in Warrick County is low, with a National Risk Index score of 65.1 out of 100 — placing it in the 65th 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.

The county's risk is driven primarily by earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $6M in expected annual loss and about 0.01 events per year; strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $2M in expected annual loss and about 4.46 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $444K in expected annual loss and about 1.03 events per year. Across all hazards, FEMA estimates $29M in expected annual loss for a population of 64K.

Beyond physical exposure, Warrick County has a very low social vulnerability rating (how susceptible the population is to harm) and a very 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: Warrick County has received 20 federal disaster declarations since 1979, including 10 for severe storm events and 4 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.

Among 92 Indiana counties, Warrick County ranks #23 for overall natural disaster risk.
