Natural disasters can occur anywhere in the United States. The East Coast is prone to hurricanes and nor’easters; the Midwest is prone to tornadoes and blizzards, the South experiences hurricanes and floods can happen in every state and territory. Then there’s California, a state known for its beautiful weather, gorgeous parks, incredible coastlines, and beaches, and of course, its propensity for natural disasters. And yet, this doesn’t stop people from flocking to certain regions to set up homes. California’s most disaster-prone cities see billion-dollar housing boom.
Many disaster-prone cities have risks, and often the risk potential is enough to make many people relocate to safer areas. Whether you already live in California or are thinking of moving to the state, it’s always important to consider the facts and weigh your pros and cons before choosing a new place to live. (For similar reading, here’s a look at the 20 most powerful earthquakes in recorded history.)
Methodology
To determine the most disaster-prone cities in California, 24/7 Tempo reviewed data on natural hazard risk for U.S. census tracts from the March 2023 FEMA National Risk Index dataset. Cities were ranked based on the average National Risk Index score – a composite risk score of 18 natural hazards: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane, ice storm, landslide, lightning, riverine flooding, strong wind, tornado, tsunami, volcanic activity, wildfire, and winter weather – for all census tracts within their borders.
Data were aggregated from the census tract level to the city level using spatial boundary definitions from the U.S. Census Bureau’s TIGER/Line program. Supplemental data on the total value of all owner-occupied homes and populations are from the U.S. Census Bureau’s American Community Survey. Only places with at least 25,000 residents were considered.
