Risk Overview

About Natural Disaster Risk in Ralls County, Missouri

Ralls County ranks among nation's safest

Ralls County's composite risk score of 14.06 places it far below the national average, earning a very low risk rating overall. While flood risk (27.16) is the county's most significant hazard, it remains modest compared to national norms, and other threats are minimal.

Second-safest county in Missouri

Ralls County's score of 14.06 ranks it just above Putnam County (8.24) as Missouri's safest counties, sitting well below the state average of 50.56. This exceptional resilience makes Ralls one of the state's most disaster-resistant communities.

Safest in its immediate region

Ralls County (14.06) is far safer than Pike County (40.30), Randolph County (35.85), and Phelps County (53.72), with only Putnam County (8.24) approaching its low-risk status. Its flood risk of 27.16 is higher than Putnam's, reflecting its proximity to the Mississippi River.

Flood risk is modest but notable

Ralls County's flood risk of 27.16 is the primary hazard, likely due to proximity to major waterways, though it remains below state averages. Wildfire (32.12) and tornado (21.18) risks are secondary concerns, while earthquake (37.34) and hurricane (10.85) risks remain low.

Standard policy covers most needs

Ralls County residents should carry standard homeowners insurance plus optional flood insurance, particularly for properties in mapped flood zones near waterways. Given the county's overall low-risk profile, additional specialized coverage is rarely necessary for most homeowners.

Risk Verdict

Compared to the nation's 3,144 counties, Ralls County ranks at the 14th percentile for natural disaster risk — toward the safer end of the spectrum. Even at the 14th percentile, Ralls County's composite score reflects real hazard exposure categories — knowing which ones apply locally enables targeted, efficient household preparedness.

Hazard Breakdown

Earthquake risk is Ralls County's dominant natural hazard, ranked at the 37th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 32th percentile nationally. Additional tracked hazards include flood (27th percentile), tornado (21th percentile), hurricane (11th percentile).

Preparedness Context

With earthquake ranked as the top hazard at the 37th percentile nationally, Ralls County residents benefit from reviewing homeowners insurance: standard policies rarely cover earthquake damage, and separate earthquake insurance must be purchased before an event. The county's wildfire risk at the 32th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Earthquake insurance in Ralls 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

At 36.5 points below the Missouri state average, Ralls County is among the lower-risk counties in the state for natural disaster exposure.
