About Natural Disaster Risk in Dubois County, Indiana

Dubois Balances Multiple Moderate Threats

Dubois County scores 59.13 on composite risk, moderately above Indiana's average of 45.52 and in the Relatively Low category nationwide. The county faces a balanced mix of hazard exposures rather than dominating risks in any single category.

Mid-Range Risk Within Indiana

Dubois ranks in the middle tier of Indiana counties by composite risk, falling below the highest-risk counties but above the safest ones. Its profile reflects typical southern Indiana hazard patterns.

Moderate Risk in Southern Indiana

Dubois's score of 59.13 positions it between low-risk counties like Franklin (34.22) and higher-risk neighbors like Floyd (75.38). Its risk level is notably lower than neighboring Elkhart County (83.75).

Earthquake Risk Is the Surprising Leader

Earthquake risk registers highest at 87.47, followed closely by flood risk at 66.06, reflecting Dubois's proximity to seismic zones and vulnerable water systems. Tornado risk at 58.75 rounds out the county's top three hazards.

Earthquake and Flood Coverage Priority

Dubois homeowners should strongly consider standalone earthquake insurance, given the county's elevated seismic risk, alongside comprehensive flood coverage. Wind and tornado protection through homeowners insurance remains essential.

Risk Verdict

At the 59th percentile nationally, Dubois County experiences a manageable level of natural hazard risk that falls below the U.S. median. Dubois County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Earthquake risk is Dubois County's dominant natural hazard, ranked at the 87th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 66th percentile nationally. Additional tracked hazards include tornado (59th percentile), hurricane (32th percentile), wildfire (17th percentile).

Preparedness Context

Dubois County's primary hazard, earthquake, ranks at the 87th percentile nationally. Unreinforced masonry structures carry the highest injury risk during seismic events; residents in older buildings should check with their municipality about available seismic retrofit programs. The county's flood risk at the 66th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. After a major earthquake, Dubois 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.

Regional Context

Dubois County falls 13.6 points above Indiana's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Dubois County higher risk than average?
Dubois County's composite risk score of 59th percentile is above the Indiana state average of 46th percentile. This elevated risk is driven by earthquake exposure (87th percentile), along with flooding and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
