Risk Overview

About Natural Disaster Risk in Lawrence County, Illinois

Lawrence County enjoys low national risk

With a composite risk score of 49.2 and a relatively low rating, Lawrence County ranks below the national average for disaster risk. This more favorable position reflects lower exposure to most common hazard types, though some risks remain.

Below-average risk within Illinois

Lawrence County's score of 49.2 falls slightly below Illinois' state average of 54.5, placing it among the lower-risk counties in the state. This relative safety makes Lawrence County one of the more resilient areas statewide.

Similar risk to nearby counties

Lawrence County's risk profile aligns closely with Logan County (58.1) and sits well below LaSalle County (86.1). The county benefits from lower exposure to most natural hazards compared to higher-risk neighbors to the north and west.

Earthquakes and floods pose concern

Lawrence County's earthquake risk of 85.5 and flood risk of 58.2 represent the county's highest hazard exposures. While wildfire risk is negligible at 0.5, residents should focus preparedness efforts on earthquake and flood readiness.

Don't skip flood and earthquake coverage

Lawrence County homeowners should secure flood insurance, particularly for properties in flood-prone areas, as standard homeowners policies exclude flood damage. Earthquake insurance is also worth evaluating, as it's typically sold separately and can provide critical protection during seismic events.

Risk Verdict

Lawrence County has a below-average natural disaster risk profile, scoring at the 49th percentile nationally under FEMA's National Risk Index.

Hazard Breakdown

Earthquake risk is Lawrence County's dominant natural hazard, ranked at the 85th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 58th percentile nationally. Additional tracked hazards include tornado (46th percentile), hurricane (22th percentile), wildfire (1th percentile).

Preparedness Context

Earthquake risk is Lawrence County's leading natural hazard, ranked at the 85th percentile nationally. Securing tall furniture, water heaters, and bookcases to walls with anti-tip hardware is among the simplest and most effective life-safety measures households can take. The county's flood risk at the 58th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Lawrence County residents should locate the main gas shutoff valve and keep an appropriate wrench nearby — gas leaks cause a significant share of earthquake-related injuries and fires, and the shutoff step is safe to take immediately after shaking stops.

Regional Context

The Illinois county average exceeds Lawrence County's score by 5.2 composite points — placing this county in the lower-risk tier relative to its in-state peers.
