Risk Overview

About Natural Disaster Risk in Saline County, Illinois

Saline maintains relatively low risk

Saline County scores 70.13 on the composite risk scale, earning a Relatively Low rating despite exceeding some Midwestern peers. The score exceeds Illinois's state average of 54.46, but remains below the dangerous thresholds seen in counties with major riverine or seismic exposure.

Mid-range risk among state counties

Saline ranks in the lower-to-middle band of Illinois counties for disaster risk, with its 70.13 score beating approximately 40% of the state. The county's earthquake risk of 94.05 is surprisingly high for Illinois, though actual seismic events remain very rare in the region.

More exposed than southern peers

Saline's 70.13 score places it above several neighboring south-central counties, though specific adjacency comparisons are limited. Its earthquake risk of 94.05 is notably elevated compared to most Illinois counties, reflecting the region's underlying geological structure rather than active seismic activity.

Tornadoes and earthquakes are top concerns

Saline faces the highest threat from tornadoes at 68.48 and earthquakes at 94.05, though earthquake damage from actual events is uncommon here. Flooding is the third concern at 57.41, while wildfire and hurricane risks remain negligible at 8.56 and 43.51 respectively.

Cover tornado, flood, and seismic damage

Saline County homeowners should obtain comprehensive coverage for tornado damage and consider earthquake insurance despite low historical activity. Maintain flood insurance through the NFIP if in a mapped flood zone, and secure heavy furniture to walls to mitigate potential earthquake damage.

Risk Advisory: Saline County

Risk Verdict

With a national percentile rank of 70th, Saline County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Earthquake risk is Saline County's dominant natural hazard, ranked at the 94th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 68th percentile nationally. Additional tracked hazards include flood (57th percentile), hurricane (44th percentile), wildfire (9th percentile).

Preparedness Context

At the 94th percentile nationally for earthquake exposure, Saline 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. Tornado at the 68th percentile nationally is a separate hazard dimension for Saline County that requires different protective strategies from earthquake preparedness. Building age matters for earthquake risk in Saline 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 15.7 points above the Illinois state average, Saline County carries meaningfully higher natural disaster exposure than a typical Illinois county.

Frequently Asked Questions

What is the natural disaster risk in Saline County, IL?
Saline County has a FEMA National Risk Index rating of Relatively Low, placing it in the 70th 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 Saline County?
Saline County is evaluated for five major natural hazard types: earthquake (94th percentile), tornado (68th percentile), flooding (57th percentile), hurricane (44th percentile), wildfire (9th percentile). The highest-risk hazard is earthquake at the 94th 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 Saline County risk compare to the Illinois average?
Saline County's composite risk percentile is 70th, compared to the Illinois state average of 55th percentile. The state's overall risk rating is Relatively Low. This means Saline County faces higher natural disaster risk than the typical county in Illinois.
Is Saline County at risk for earthquake?
Yes, Saline County's earthquake risk is at the 94th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Saline County is at the 57th 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 Saline County higher risk than average?
Saline County's composite risk score of 70th percentile is above the Illinois state average of 55th percentile. This elevated risk is driven by earthquake exposure (94th 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.
