Risk Overview

About Natural Disaster Risk in La Paz County, Arizona

La Paz County faces moderate risks

La Paz County scores 83.52 on the composite risk scale, placing it in the "Relatively Moderate" category and nearly at Arizona's state average of 84.45. The southwestern county contends with multiple overlapping hazards that demand preparation.

Close to Arizona's average risk

La Paz County tracks nearly at the Arizona state average, positioned in the moderate-risk tier. Its 83.52 score reflects a balanced mix of flood, earthquake, and wildfire exposure typical of western Arizona.

Moderate risk within the region

La Paz County's 83.52 score is notably higher than Greenlee County (12.37) to the east but comparable to Maricopa County (99.87) in overall magnitude. Its western position exposes it to different hazard patterns than the state's mountainous regions.

Flood and earthquake are top concerns

La Paz County faces high flood risk (91.48) and significant earthquake exposure (79.04), making these the primary hazards. Wildfire risk (70.17) is notably lower than in Arizona's mountain counties but still warrants attention.

Prioritize flood and earthquake coverage

La Paz County residents should secure flood insurance given the 91.48 risk score, particularly for properties in flood-prone areas. Earthquake insurance is also recommended to protect against the county's 79.04 seismic exposure.

Hazard Breakdown

Flood risk is La Paz County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 79th percentile nationally. Additional tracked hazards include wildfire (70th percentile), hurricane (17th percentile), tornado (5th percentile).

Preparedness Context

With flood risk ranking at the 91th percentile nationally, La Paz County residents face one of the most financially damaging hazards without specialized coverage.

La Paz County's secondary hazard, earthquake at the 79th percentile nationally, indicates that compounding hazard types require layered preparation strategies, not single-peril planning. Registering for La Paz County's county emergency alert system — typically through the county emergency management office's website — ensures households receive early warning when flood events develop faster than forecast.

Regional Context

La Paz County tracks the Arizona county average closely, sitting 0.9 composite points below the state mean — neither a standout high-risk nor low-risk county within Arizona.
