Risk Overview

About Natural Disaster Risk in Clarke County, Georgia

Clarke balances moderate and elevated risks

Clarke County's composite risk score of 66.95 places it above the national average with a relatively low risk rating, reflecting a mixed hazard profile. Tornado (79.42), hurricane (71.34), and earthquake (83.33) risks are all notable, while wildfire exposure (25.64) is minimal. The county's central Georgia location creates exposure to multiple hazard types without coastal vulnerability.

Above-average risk for Georgia

Clarke's 66.95 composite score exceeds Georgia's state average of 39.49 by nearly 70 percent, placing it in the upper-middle tier of state county risk. Earthquake risk (83.33) is particularly elevated for inland Georgia, reflecting the county's proximity to Appalachian seismic zones. Tornado risk (79.42) aligns with the state's general convective weather exposure.

Moderate risk within central Georgia

Clarke's 66.95 score exceeds Chattooga (54.36) and Chattahoochee (2.04) but falls below Cherokee (85.27) and Chatham (97.42) in the broader regional context. The county occupies a moderate-risk position in central Georgia, with earthquake exposure slightly higher than typical for the region. This profile distinguishes Clarke from both its low-risk western neighbors and high-risk eastern/northern peers.

Earthquake and tornado, with hurricane distant

Earthquake risk (83.33) is Clarke's most notable hazard, ranking high for Georgia and reflecting the county's position near Appalachian fault zones, though major seismic events remain historically rare. Tornado risk (79.42) follows closely, with spring severe weather a routine concern. Hurricane risk (71.34) is elevated but reflects distant impacts rather than direct coastal exposure.

Earthquake and tornado awareness matter most

Confirm your homeowners policy includes wind/hail coverage for tornado risk (79.42), and consider flood insurance if your property sits near mapped floodplains or the Oconee River. While earthquake risk (83.33) is higher than most Georgia counties, standard homeowners policies exclude seismic damage—separate earthquake insurance is available but typically optional unless in a mapped risk zone. Secure heavy furniture and water heaters to foundation bracing as practical earthquake mitigation.

Risk Advisory: Clarke County

Risk Verdict

Clarke County's FEMA risk score places it at the 67th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Earthquake risk is Clarke County's dominant natural hazard, ranked at the 83th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 79th percentile nationally. Additional tracked hazards include hurricane (71th percentile), flood (71th percentile), wildfire (26th percentile).

Preparedness Context

With earthquake ranked as the top hazard at the 83th percentile nationally, Clarke County residents benefit from reviewing homeowners insurance: standard policies rarely cover earthquake damage, and separate earthquake insurance must be purchased before an event. Alongside earthquake exposure, Clarke County's tornado risk at the 79th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Earthquake insurance in Clarke County is typically offered as a separate policy — standard homeowners coverage excludes ground movement. Reviewing this gap and comparing policy options before an event is a financial preparedness step with potentially large consequences.

Regional Context

The Georgia county average is 27.5 composite points below Clarke County's score, a gap that reflects the county's elevated position in the state's hazard distribution.

Frequently Asked Questions

What is the natural disaster risk in Clarke County, GA?
Clarke County has a FEMA National Risk Index rating of Relatively Low, placing it in the 67th 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 Clarke County?
Clarke County is evaluated for five major natural hazard types: earthquake (83th percentile), tornado (79th percentile), hurricane (71th percentile), flooding (71th percentile), wildfire (26th percentile). The highest-risk hazard is earthquake at the 83th 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 Clarke County risk compare to the Georgia average?
Clarke County's composite risk percentile is 67th, compared to the Georgia state average of 40th percentile. The state's overall risk rating is Very Low. This means Clarke County faces higher natural disaster risk than the typical county in Georgia.
Is Clarke County at risk for earthquake?
Yes, Clarke County's earthquake risk is at the 83th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Clarke County is at the 71th 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.
Why is Clarke County higher risk than average?
Clarke County's composite risk score of 67th percentile is above the Georgia state average of 40th percentile. This elevated risk is driven by earthquake exposure (83th percentile), along with tornado and hurricane and flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
