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.
