Mid-range risk within Colorado

San Miguel's 19.12 score is less than half the Colorado state average of 40.67, reflecting notably lower overall hazard exposure. The county ranks in the lower-to-middle tier among its peers statewide.

Less risky than mountain neighbors

San Miguel scores lower than Summit County (60.21) and Teller County (38.84), but higher than nearby San Juan (10.69) and Sedgwick (6.52). It represents a moderate risk profile for the southwestern Colorado region.

Wildfire dominates, followed by flooding

Wildfire insurance is essential here

Risk Verdict

San Miguel County's natural disaster risk is among the lowest in the country, with a composite score at the 19th percentile nationally.

Hazard Breakdown

Wildfire risk is San Miguel County's dominant natural hazard, ranked at the 80th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 32th percentile nationally. Additional tracked hazards include earthquake (31th percentile), tornado (3th percentile).

Preparedness Context

Wildfire is San Miguel County's top-ranked natural hazard at the 80th percentile nationally. San Miguel County residents should assess whether their property lies within or adjacent to a Wildland-Urban Interface (WUI) zone, where ember transport and rapid spread pose the highest risk. The county's flood exposure at the 32th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. For San Miguel County households, a practiced evacuation plan — with a primary and backup route designated before a fire occurs — provides more protection than any structural improvement when a wildfire approaches fast-moving terrain.

Regional Context

The Colorado county average exceeds San Miguel County's score by 21.6 composite points — placing this county in the lower-risk tier relative to its in-state peers.
