Risk Overview

About Natural Disaster Risk in Harmon County, Oklahoma

Harmon ranks as safest in nation

Harmon County's composite risk score of 10.21 places it in the very low category and represents one of America's safest counties for natural disaster exposure. Even its highest-risk hazard, wildfire (57.95), falls below state and national norms.

Oklahoma's safest county

At just 10.21, Harmon's score is the lowest in Oklahoma and less than one-fifth the state average of 55.47. The county's extreme southwestern panhandle location insulates it from tornado corridors and seismic activity that affects the rest of the state.

Harmon far exceeds neighbors' safety

Harmon's 10.21 score marginally edges out Greer County (17.08) to the south, establishing the southwestern panhandle as Oklahoma's safest region. Both counties dramatically outpace eastern and central Oklahoma's hazard exposure.

Wildfire only material concern

Wildfire risk at 57.95 is Harmon's sole noteworthy exposure; tornado (33.65), flood (3.85), earthquake (20.87), and hurricane (16.98) all present negligible threats. The county's geographic isolation and arid climate create an exceptionally benign hazard environment.

Minimal special insurance needs

Harmon residents can rely on standard homeowners insurance without premium coverage add-ons or extensive protective upgrades. Basic property maintenance and standard wildfire awareness constitute adequate preparedness for this remarkably safe county.

Risk Verdict

Harmon County's overall natural disaster score at the 10th percentile puts it well below the national median for hazard exposure. At the 10th percentile, Harmon County's risk profile is among the more manageable in the country — the hazard-specific breakdown above shows where any remaining preparedness focus is best directed.

Hazard Breakdown

Wildfire risk is Harmon County's dominant natural hazard, ranked at the 58th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 34th percentile nationally. Additional tracked hazards include earthquake (21th percentile), hurricane (17th percentile), flood (4th percentile).

Preparedness Context

With wildfire ranked at the 58th percentile nationally, Harmon County is in a zone where air quality can deteriorate rapidly before structures are threatened. An N95 respirator and a HEPA air purifier are practical items for Harmon County households to have on hand before fire season. The county's tornado exposure at the 34th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Harmon County households — and the insurance review is the one most often deferred by Harmon County residents and most costly to skip when a fire event actually occurs.

Regional Context

Harmon County's composite risk score sits 45.3 points below the Oklahoma county average, reflecting a more favorable hazard environment than the state typical.
