Orange County sits between the Santa Ana Mountains and the Pacific Ocean, creating wildfire corridors that have produced some of Southern California's most destructive fires. The 2007 Santiago Fire burned over 28,000 acres. Coastal areas face tsunami risk from Pacific subduction zone events, and the county sits near multiple active fault systems.
