Risk Overview

About Natural Disaster Risk in Jackson County, Arkansas

Jackson's tornado and earthquake risks soar

Jackson County's composite risk score of 67.84 rates as Relatively Low nationally, but this masks dangerous concentration in two hazards: tornado risk at 89.63 and earthquake risk at 91.60. Both scores significantly exceed the state average of 55.51.

Top 10 riskiest Arkansas counties

Jackson County ranks among Arkansas's highest-risk counties, primarily driven by extreme tornado and earthquake exposure. Only a handful of Arkansas counties face comparable combined tornado and seismic threats.

Tornado risk dwarfs regional peers

Jackson's tornado score of 89.63 far exceeds Izard County's 59.61 and Lawrence County's 83.46. Its earthquake risk of 91.60 matches Jefferson County's dangerous exposure, making Jackson one of the state's seismic hotspots.

Tornadoes and earthquakes dominate

Jackson's tornado risk score of 89.63 represents the county's most acute hazard—well above the state average. Earthquake risk at 91.60 ranks second and alone would classify most counties as high-risk.

Earthquake and storm coverage essential

Jackson County residents absolutely need earthquake insurance given the 91.60 risk score—standard policies exclude it entirely. Add windstorm coverage to your homeowners policy to protect against tornado damage and hail.

Jackson County sits below the national average for natural disaster exposure, ranking at the 68th percentile across all U.S. counties. Understanding the specific hazards behind Jackson County's ranking helps residents prioritize where to direct emergency planning efforts.

Hazard Breakdown

Earthquake risk is Jackson County's dominant natural hazard, ranked at the 92th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 90th percentile nationally. Additional tracked hazards include hurricane (54th percentile), wildfire (44th percentile), flood (44th percentile).

Preparedness Context

At the 92th percentile nationally for earthquake risk, Jackson County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. Alongside earthquake exposure, Jackson County's tornado risk at the 90th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. For Jackson County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.

Regional Context

A composite score 12.3 points above the Arkansas state average puts Jackson County in a higher-risk category than most counties in the state.
