Risk Overview

About Natural Disaster Risk in Greenlee County, Arizona

Greenlee County has minimal risk

Greenlee County scores just 12.37 on the composite risk scale, earning a "Very Low" rating and placing it far below Arizona's state average of 84.45. The northeastern county is among the safest areas in the nation for natural disasters.

Safest county in Arizona

Greenlee County ranks as Arizona's lowest-risk county by a significant margin, with a composite score less than one-sixth of the state average. This exceptional safety makes it unique among Arizona's natural hazard exposure profile.

Dramatically safer than all neighbors

Greenlee County's 12.37 score is dramatically lower than Apache County (78.78) to the west and Graham County (64.60) to the south. Its minimal exposure stands out starkly against the higher-risk counties surrounding it.

Wildfire is the only notable concern

Greenlee County's sole significant hazard is wildfire risk at 82.51, stemming from the county's forested areas. All other natural disasters—flood, tornado, earthquake, and hurricane—score well below regional and national averages.

Wildfire coverage for peace of mind

Even in Greenlee County's low-risk environment, wildfire insurance remains worthwhile given the 82.51 risk score. Standard homeowners policies exclude wildfire, so supplemental coverage ensures full protection.

Greenlee County's natural disaster risk is among the lowest in the country, with a composite score at the 12th percentile nationally. The 12th percentile national ranking is one lens; Greenlee County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Wildfire risk is Greenlee County's dominant natural hazard, ranked at the 83th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 30th percentile nationally. Additional tracked hazards include earthquake (22th percentile), hurricane (7th percentile), tornado (1th percentile).

Preparedness Context

Wildfire is Greenlee County's top-ranked natural hazard at the 83th percentile nationally. Greenlee 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. Alongside wildfire, flood at the 30th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. For Greenlee 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 Arizona county average exceeds Greenlee County's score by 72.1 composite points — placing this county in the lower-risk tier relative to its in-state peers.
