Environmental Risk Report for Tehama County, California

Tehama County is a county in CA known for its varied climate ranging from Mediterranean on the coast to alpine in the mountains. Its coastal location provides beautiful scenery but also creates unique vulnerability to storm surge and coastal flooding.

Tehama County exists within one of the most seismically active regions in North America. The San Andreas Fault system and its associated branches run through much of the state, capable of producing magnitude 7.0+ earthquakes. Combined with annual wildfire seasons that have grown increasingly destructive, residents face a dual-threat environment that demands comprehensive emergency preparedness.

Notable historical events affecting this area include the 1906 Great San Francisco Earthquake (Magnitude 7.9, ~3,000 deaths, destroyed 80% of San Francisco); the 1989 Loma Prieta Earthquake (Magnitude 6.9, 63 deaths, $6B in damage across the Bay Area); the 1994 Northridge Earthquake (Magnitude 6.7, 57 deaths, $20B in damage in Los Angeles area). These events underscore the importance of environmental risk awareness and preparedness for residents and property owners.

California leads the nation in both earthquake and wildfire risk, with diverse geography ranging from coastal bluffs to Sierra Nevada peaks. The state's 39 million residents face a unique combination of natural hazards driven by its Mediterranean climate, active fault lines, and extensive wildland-urban interface.
