Risk Overview

About Natural Disaster Risk in Ellis County, Kansas

Ellis County matches national safety baseline

Ellis County's composite risk score of 32.70 earns a Very Low rating and sits just slightly above the national average, indicating moderate but manageable disaster risk. Residents face typical hazards for a rural Great Plains county.

Slightly above Kansas average for risk

At 32.70, Ellis County edges above Kansas's state average of 29.89, placing it in the middle range of the state's 105 counties. The difference is modest—many Kansas counties face greater combined hazard exposure.

Comparable risk to surrounding counties

Ellis County's profile closely mirrors that of nearby Trego and Graham counties, with tornado and wildfire presenting shared regional threats. Flood risk remains moderate across this central Kansas region.

Tornadoes and wildfires dominate hazard mix

Tornado risk scores 57.63 and wildfire risk reaches 60.69, making these Ellis County's primary natural disaster concerns. Flooding presents secondary risk at 34.45, while earthquake and hurricane dangers remain negligible.

Standard homeowners policy covers tornadoes

A comprehensive homeowners insurance policy protects against tornado damage, while considering a wildfire rider provides additional coverage for brush fires. Given moderate flooding risk, reviewing flood insurance eligibility is prudent.

Risk Verdict

Ellis County's overall natural disaster score at the 33th percentile puts it well below the national median for hazard exposure. The 33th percentile national ranking is one lens; Ellis County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Wildfire risk is Ellis County's dominant natural hazard, ranked at the 61th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 58th percentile nationally. Additional tracked hazards include flood (34th percentile), earthquake (23th percentile).

Preparedness Context

With wildfire ranked at the 61th percentile nationally, Ellis County is in a zone where air quality can deteriorate rapidly before structures are threatened. An N95 respirator and a HEPA air purifier are practical items for Ellis County households to have on hand before fire season. A secondary tornado exposure at the 58th percentile nationally means Ellis County residents face hazards from two distinct natural peril categories during different seasons. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Ellis County households — and the insurance review is the one most often deferred by Ellis County residents and most costly to skip when a fire event actually occurs.

Regional Context

Ellis County's risk score is broadly comparable to the Kansas county average, with a 2.8-point gap that places the county near the center of the state's hazard distribution.

What types of natural hazards affect Ellis County?
Ellis County is evaluated for five major natural hazard types: wildfire (61th percentile), tornado (58th percentile), flooding (34th percentile), earthquake (23th percentile). The highest-risk hazard is wildfire at the 61th 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 Ellis County risk compare to the Kansas average?
Ellis County's composite risk percentile is 33th, compared to the Kansas state average of 30th percentile. The state's overall risk rating is Very Low. This means Ellis County faces higher natural disaster risk than the typical county in Kansas.

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 Ellis County higher risk than average?
Ellis County's composite risk score of 33th percentile is above the Kansas state average of 30th percentile. This elevated risk is driven by wildfire exposure (61th percentile), along with tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
