Risk Overview

About Natural Disaster Risk in Oliver County, North Dakota

Oliver County's risk ranks very low

With a composite risk score of 1.72, Oliver County faces significantly lower natural disaster risk than the typical U.S. county. This very low rating reflects relatively modest exposure across most hazard types, though wildfire and tornado risks merit monitoring in this region.

Among North Dakota's safest counties

Oliver County ranks in the lowest tier statewide with a composite score well below North Dakota's 22.19 county average. Only a handful of ND counties face less overall natural disaster risk.

Safer than surrounding areas

Oliver County's 1.72 composite score is substantially lower than nearby Pierce County (3.24) and Ransom County (13.20). The county benefits from lower flood and tornado exposure compared to eastern neighbors in the Red River Valley region.

Wildfire is your primary concern

Wildfire risk scores 44.47—the highest hazard facing Oliver County—though this remains moderate in regional context. Tornado risk (11.74) and flood risk (6.52) rank considerably lower but shouldn't be overlooked during severe weather seasons.

Cover wildfire and severe weather

Standard homeowners insurance typically covers tornado damage but often excludes wildfire loss. Review your policy to ensure wildfire coverage is included, and consider additional protection for fire-prone areas; standard flood insurance remains advisable even with low current risk.

Risk Verdict

Natural disaster exposure in Oliver County is lower than roughly three-quarters of U.S. counties, with a composite score at the 2th percentile. A 2th percentile score positions Oliver County among the nation's lower-risk counties, a genuinely favorable outcome — one that simple, low-cost preparedness habits can reinforce further.

Hazard Breakdown

Wildfire risk is Oliver County's dominant natural hazard, ranked at the 44th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 12th percentile nationally. Additional tracked hazards include flood (7th percentile), earthquake (0th percentile).

Preparedness Context

At the 44th percentile nationally for wildfire, Oliver County residents should verify whether their insurance policy includes replacement cost coverage for structures and whether the insurer still writes new policies in this fire-risk zone. The county's tornado exposure at the 12th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Local USFS or Cal Fire (where applicable) fire risk maps and seasonal Red Flag Warning alerts from the National Weather Service are two free resources Oliver County residents can use to stay ahead of rapidly changing wildfire conditions.

Regional Context

Oliver County is 20.5 composite risk points below the North Dakota state mean, meaning most other North Dakota counties face higher natural hazard exposure.
