About Natural Disaster Risk in Ouachita County, Arkansas

Ouachita County faces above-average national risks

Ouachita County scores 51.21, placing it in the Relatively Low category but above the national average for composite risk. This elevation reflects notably higher exposure to certain natural hazards, particularly earthquakes and tornadoes.

Mid-range risk within Arkansas

At 51.21, Ouachita County sits just below Arkansas's average of 55.51, positioning it roughly in the middle of state risk rankings. The county's profile reflects moderate exposure to multiple hazard types, particularly earthquake and tornado threats.

Higher risk than surrounding counties

Ouachita County's 51.21 score significantly exceeds nearby Nevada County (30.57), Perry County (28.05), and Pike County (26.56). This difference makes Ouachita a notable risk outlier within its region, driven primarily by earthquake and tornado exposure.

Tornadoes and earthquakes demand attention

Ouachita County faces substantial tornado risk at 70.07 and extreme earthquake risk at 79.87, making these the county's primary natural hazard concerns. Flood risk (53.05) and hurricane risk (56.15) also exceed state averages, though tornado and earthquake threats dominate the profile.

Comprehensive coverage essential here

Ouachita County residents should maintain robust tornado coverage and strongly consider earthquake insurance given the county's 79.87 earthquake risk score. Flood and hurricane insurance should also be reviewed to ensure complete protection across all major hazard types.

Preparedness Context

Earthquake risk is Ouachita County's leading natural hazard, ranked at the 80th percentile nationally. Securing tall furniture, water heaters, and bookcases to walls with anti-tip hardware is among the simplest and most effective life-safety measures households can take. Alongside earthquake exposure, Ouachita County's tornado risk at the 70th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Ouachita County residents should locate the main gas shutoff valve and keep an appropriate wrench nearby — gas leaks cause a significant share of earthquake-related injuries and fires, and the shutoff step is safe to take immediately after shaking stops.
