Risk Overview

About Natural Disaster Risk in Greene County, Arkansas

Greene County's elevated earthquake risk dominates

Greene County's composite risk score of 80.18 reflects a Relatively Low national rating, but masks severe earthquake exposure at 95.71—among the highest in the country. Tornado risk at 87.88 adds a second major hazard residents must prepare for.

Above-average risk for Arkansas county

Greene County's score of 80.18 significantly exceeds Arkansas's state average of 55.51, placing it firmly in the upper half of state risk rankings. This elevated position is driven almost entirely by exceptional earthquake and tornado vulnerability.

Most seismically active county in region

Greene County's earthquake score of 95.71 far surpasses neighboring Independence County (89.98) and all other regional peers, making it the region's seismic hotspot. Its tornado risk at 87.88 also exceeds most surrounding counties.

Earthquake and tornado risk define Greene County

Earthquake risk at 95.71 is Greene County's primary concern, with tornado exposure at 87.88 running a close second—creating a dangerous one-two punch. Flood risk at 63.23 remains moderate but cannot be ignored during spring storms.

Earthquake insurance is non-negotiable here

Greene County residents must secure dedicated earthquake coverage as a priority—it's not included in standard homeowner's policies and your risk level justifies the investment. Pair this with robust wind and hail coverage, and ensure your home's foundation and structural connections are professionally evaluated and reinforced.

Risk Advisory: Greene County

Risk Verdict

With a national percentile rank of 80th, Greene County faces below-average hazard exposure relative to U.S. counties as a whole. Proactive preparedness — not reactive response — is key to managing life in one of the country's higher-risk counties; Greene County residents should plan accordingly.

Hazard Breakdown

Earthquake risk is Greene County's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 88th percentile nationally. Additional tracked hazards include flood (63th percentile), hurricane (46th percentile), wildfire (30th percentile).

Preparedness Context

At the 96th percentile nationally for earthquake exposure, Greene County households benefit from practicing Drop, Cover, and Hold On — the protocol that minimizes injury during shaking. Getting under a sturdy table or desk and holding on until shaking stops is the key action. Alongside earthquake exposure, Greene County's tornado risk at the 88th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Building age matters for earthquake risk in Greene County: structures built before local seismic code adoption are statistically more vulnerable. Contacting the local building department about retrofit programs can reveal whether your structure qualifies for mitigation assistance.

Regional Context

At 24.7 points above the Arkansas state average, Greene County carries meaningfully higher natural disaster exposure than a typical Arkansas county.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Greene County higher risk than average?
Greene County's composite risk score of 80th percentile is above the Arkansas state average of 56th percentile. This elevated risk is driven by earthquake exposure (96th percentile), along with tornado and flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
