Risk Overview
About Natural Disaster Risk in Millard County, Utah
Millard County poses low disaster risk nationally
Millard County's composite risk score of 22.17 falls into the Very Low category, approximately 40% below Utah's state average of 36.19. This central Utah county enjoys below-average exposure to natural hazards.
Fourth-lowest risk in Utah
Among Utah's 29 counties, Millard ranks toward the lower end of disaster exposure, ahead of Juab (15.30), Grand (10.27), and Piute (0.89). Its remote desert location contributes to this favorable positioning.
Safer than most surrounding counties
Millard's 22.17 score makes it safer than Garfield (37.63), Juab (15.30 but with higher wildfire), and Piute (0.89 only slightly lower). It occupies a middle ground in the central Utah risk landscape.
Wildfire and earthquake are primary concerns
Wildfire risk scores 91.22, among the state's highest, making brush fires Millard's dominant hazard despite its low composite score. Earthquake risk (83.24) ranks second, reflecting the county's position in seismically active central Utah.
Prioritize wildfire and quake coverage
Though Millard County's overall risk is low, concentrated hazards—particularly wildfire—warrant dedicated insurance unavailable through standard policies. Residents should secure wildfire and earthquake riders while maintaining defensible space and emergency preparedness plans.

Preparedness Context
At the 91th percentile nationally for wildfire, Millard 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 earthquake exposure at the 83th 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 Millard County residents can use to stay ahead of rapidly changing wildfire conditions.
Regional Context
Millard County is 14.0 composite risk points below the Utah state mean, meaning most other Utah counties face higher natural hazard exposure.
