Risk Overview
FEMA's National Risk Index rates Shelby County at low composite risk, with a National Risk Index score of 43.4 out of 100 — placing it in the 43rd 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.
Most of Shelby County's expected losses come from 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 — $1M 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 — $467K in expected annual loss and about 4.17 events per year. Across all hazards, FEMA estimates $16M in expected annual loss for a population of 45K.
Beyond physical exposure, Shelby County has a very 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: Shelby County has received 14 federal disaster declarations since 1974, including 5 for severe storm events and 2 for biological events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 92 Indiana counties, Shelby County ranks #44 for overall natural disaster risk.
