Mid-range risk in southern region

Rio Grande County (45.77) faces lower risk than Pueblo County (82.51) but higher than Routt County (33.37) and Saguache County (14.25). The county's south-central location creates moderate exposure compared to neighboring areas.

Earthquakes and wildfires loom

Hazard Breakdown

Earthquake risk is Rio Grande County's dominant natural hazard, ranked at the 69th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 64th percentile nationally. Additional tracked hazards include flood (55th percentile), tornado (14th percentile).

Preparedness Context

At the 69th percentile nationally for earthquake risk, Rio Grande County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. Wildfire at the 64th percentile nationally is a separate hazard dimension for Rio Grande County that requires different protective strategies from earthquake preparedness. For Rio Grande County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.

Regional Context

A composite score 5.1 points above the Colorado state average puts Rio Grande County in a higher-risk category than most counties in the state.
