Hazard Breakdown
Tornado risk is Jasper County's dominant natural hazard, ranked at the 70th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 53th percentile nationally. Additional tracked hazards include flood (40th percentile), earthquake (28th percentile), hurricane (12th percentile).
Preparedness Context
With tornado ranked at the 70th percentile nationally, Jasper County sits in a high-exposure zone where the difference between outcomes often comes down to proximity to a reinforced interior shelter and seconds of warning time. Alongside tornado exposure, wildfire at the 53th percentile nationally means Jasper County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. For Jasper County households, safe rooms certified to FEMA 320/361 standards offer the highest protection during a direct tornado hit; households without a safe room should locate the innermost lowest-floor room in their building and practice the route to it before storm season.
Regional Context
Jasper County's risk score is broadly comparable to the Iowa county average, with a 4.0-point gap that places the county near the center of the state's hazard distribution.
