Risk Overview

About Natural Disaster Risk in McPherson County, Kansas

McPherson County's disaster risk

McPherson County scores 39.22 on the composite risk scale, earning a Very Low rating while exceeding Kansas's state average of 29.89. This moderate exposure places the county in a manageable risk tier nationally.

Above-average risk for Kansas

McPherson County ranks above the state median among Kansas's 105 counties, reflecting notably higher tornado exposure than most of its peers. Its Very Low rating still indicates manageable overall hazard exposure statewide.

Highest-risk neighbor in cluster

McPherson County's 39.22 score edges out Marion County (37.98) and far exceeds Marshall County (21.41) in the immediate neighborhood. Its elevated tornado risk (77.10) significantly outpaces both neighbors' storm exposure.

Tornado threat leads all hazards

Risk Verdict

At the 39th percentile nationally, McPherson County experiences relatively limited natural hazard pressure compared to most of the country. Even at the 39th percentile, McPherson County's composite score reflects real hazard exposure categories — knowing which ones apply locally enables targeted, efficient household preparedness.

Hazard Breakdown

Tornado risk is McPherson County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 67th percentile nationally. Additional tracked hazards include flood (33th percentile), earthquake (24th percentile), hurricane (0th percentile).

Preparedness Context

McPherson County ranks at the 77th percentile nationally for tornado exposure. Unlike many slow-onset hazards, tornadoes in McPherson County can reach full intensity in minutes; a pre-practiced household shelter plan matters far more than stockpiled supplies. Alongside tornado exposure, wildfire at the 67th percentile nationally means McPherson County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. McPherson County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.

Regional Context

Compared to other Kansas counties, McPherson County runs 9.3 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.

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 McPherson County higher risk than average?
McPherson County's composite risk score of 39th percentile is above the Kansas state average of 30th percentile.
