Risk Overview
About Natural Disaster Risk in Santa Barbara County, California
Santa Barbara faces very high disaster risk
Santa Barbara County's composite risk score of 98.98 places it firmly above the national average with a 'Relatively High' rating. The county confronts serious exposure to multiple natural hazards, with particularly acute wildfire and earthquake threats.
Among the state's most vulnerable counties
Santa Barbara's 98.98 score significantly exceeds California's 88.72 average, marking it as one of the state's highest-risk counties. The county's coastal position and mountainous terrain combine to amplify hazard exposure.
Wildfire risk exceeds nearby counties
Santa Barbara (98.98) faces notably higher wildfire risk (99.20) than most neighboring coastal counties, though comparable overall risk to San Luis Obispo and Ventura. The county's chaparral-covered hillsides create particularly acute fire conditions during drought seasons.
Wildfires and earthquakes dominate here
Wildfire risk reaches 99.20 in Santa Barbara—among California's absolute highest—while earthquake risk scores 99.36, threatening infrastructure and homes countywide. Flood risk (98.63) completes a triple threat, with coastal and foothill residents at particular vulnerability.
Wildfire and earthquake insurance non-negotiable
Santa Barbara residents must secure standalone wildfire and earthquake insurance, as standard homeowners policies exclude both. Given the county's 99.20 wildfire risk, defensible space maintenance and evacuation planning are equally critical to insurance coverage.

Hazard Breakdown
Earthquake risk is Santa Barbara County's dominant natural hazard, ranked at the 99th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 99th percentile nationally. Additional tracked hazards include flood (99th percentile), tornado (5th percentile), hurricane (0th percentile).
Preparedness Context
Earthquake risk is Santa Barbara County's leading natural hazard, ranked at the 99th 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. Wildfire at the 99th percentile nationally is a separate hazard dimension for Santa Barbara County that requires different protective strategies from earthquake preparedness. Santa Barbara 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.
Regional Context
Santa Barbara County's composite risk score sits 10.3 points above the California county average, placing it among the more hazard-exposed counties in the state.
