At the 20th percentile nationally, Brown County experiences relatively limited natural hazard pressure compared to most of the country. Even at the 20th percentile, Brown County's composite score reflects real hazard exposure categories — knowing which ones apply locally enables targeted, efficient household preparedness.

Hazard Breakdown

Tornado risk is Brown County's dominant natural hazard, ranked at the 51th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 42th percentile nationally. Additional tracked hazards include flood (38th percentile), wildfire (8th percentile), hurricane (7th percentile).

Preparedness Context

Brown County ranks at the 51th percentile nationally for tornado exposure. Unlike many slow-onset hazards, tornadoes in Brown County can reach full intensity in minutes; a pre-practiced household shelter plan matters far more than stockpiled supplies. Alongside tornado exposure, earthquake at the 42th percentile nationally means Brown County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. Brown 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

A composite score 25.8 points below the Indiana state average puts Brown County in a better-than-typical position relative to neighboring counties.
