Risk Overview

About Natural Disaster Risk in Oregon County, Missouri

Oregon County faces moderate earthquake risk

Oregon County's composite risk score of 48.70 places it near the national average, but masks a distinctive hazard profile dominated by earthquake risk at 82.44. This elevated seismic exposure, combined with moderate wildfire risk of 60.11, creates a different vulnerability pattern than many U.S. counties.

Oregon ranks slightly below state average

Oregon County's composite risk score of 48.70 sits just below Missouri's state average of 50.56, yet its earthquake risk of 82.44 is among the highest statewide. This unusual seismic threat reflects the county's proximity to the New Madrid Seismic Zone, a major fault system spanning multiple states.

Oregon's earthquake risk stands out

Oregon County's earthquake risk of 82.44 substantially exceeds that of nearby Howell and Shannon counties, making it a seismic outlier in the Ozark region. While tornado risk resembles neighbors at 61.99, the earthquake exposure creates a unique risk calculus for property and emergency planning.

Earthquakes and wildfires pose greatest threats

Oregon County faces exceptional earthquake risk at 82.44, the highest hazard in the county and well above most Missouri locations due to New Madrid Seismic Zone proximity. Wildfire risk at 60.11 compounds this exposure, particularly for properties in forested or mountainous areas of the Ozarks.

Earthquake-proof your property

Oregon County homeowners should secure heavy furniture and appliances, brace water heaters, and ensure adequate earthquake insurance coverage or special endorsements. Wildfire exposure demands defensible space maintenance and confirmation that homeowner policies include wildfire protection, especially for rural properties.

Risk Advisory: Oregon County

Risk Verdict

With a national percentile rank of 49th, Oregon County faces below-average hazard exposure relative to U.S. counties as a whole. At the 49th percentile nationally, Oregon County's natural hazard profile is comparatively favorable — community resilience is reinforced when individual households maintain a reviewed emergency plan.

Hazard Breakdown

Earthquake risk is Oregon County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 62th percentile nationally. Additional tracked hazards include wildfire (60th percentile), flood (46th percentile), hurricane (37th percentile).

Preparedness Context

At the 82th percentile nationally for earthquake exposure, Oregon 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. The county's tornado risk at the 62th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Building age matters for earthquake risk in Oregon 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

Oregon County tracks the Missouri county average closely, sitting 1.9 composite points below the state mean — neither a standout high-risk nor low-risk county within Missouri.

Frequently Asked Questions

What is the natural disaster risk in Oregon County, MO?
Oregon County has a FEMA National Risk Index rating of Relatively Low, placing it in the 49th percentile nationally out of 3,144 counties. This composite score reflects the county's overall exposure to natural hazards including floods, wildfires, tornadoes, earthquakes, and hurricanes, weighted by expected annual loss and social vulnerability.
What types of natural hazards affect Oregon County?
Oregon County is evaluated for five major natural hazard types: earthquake (82th percentile), tornado (62th percentile), wildfire (60th percentile), flooding (46th percentile), hurricane (37th percentile). The highest-risk hazard is earthquake at the 82th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Oregon County risk compare to the Missouri average?
Oregon County's composite risk percentile is 49th, compared to the Missouri state average of 51th percentile. The state's overall risk rating is Relatively Low. This means Oregon County faces lower natural disaster risk than the typical county in Missouri.
Is Oregon County at risk for earthquake?
Yes, Oregon County's earthquake risk is at the 82th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Oregon County is at the 46th percentile.
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.
Is Oregon County a safe place to live?
Oregon County's composite risk score of 49th percentile is below the Missouri state average of 51th percentile, indicating relatively lower exposure to natural hazards. However, no county is completely risk-free. The primary hazard type is earthquake at the 82th percentile. Residents should still maintain emergency preparedness plans and appropriate insurance coverage.
