Risk Overview
About Natural Disaster Risk in Shelby County, Ohio
Shelby ranks near national average
Shelby County's composite risk score of 56.20 places it in the relatively low category, just slightly above the national average for disaster risk. This balanced profile means residents face moderate exposure comparable to most American counties.
Near Ohio's state average risk
Shelby County's 56.20 score sits just above Ohio's state average of 55.03, making it a fairly typical Ohio county in terms of natural disaster risk. It ranks in the middle tier of Ohio's 88 counties by risk level.
Shelby sits between high and low-risk neighbors
Shelby's 56.20 score falls between the very-low-risk Union County (32.73) and the higher-risk Stark County (87.95), positioning it as an average-risk area regionally. Its distinctive earthquake risk of 86.55 is notably higher than neighboring counties.
Earthquakes and tornadoes lead threats
Shelby County faces unusual earthquake risk at 86.55—among Ohio's highest—combined with strong tornado risk of 68.54. Flood risk of 63.33 adds a third concern, though wildfire remains minimal at 10.34.
Earthquake and storm protection essential
Shelby residents should prioritize earthquake insurance and verify their homeowner's policy covers tornado and wind damage thoroughly. Earthquake insurance requires a separate policy and protects against Shelby's unusually high seismic risk.

After a major earthquake, Shelby County residents should expect water service disruption for 24 to 72 or more hours. Storing a minimum of one gallon per person per day for three days — before any event — is the most direct preparedness action households can take.
