One address can have several hazard layers

An address can sit in more than one map layer. In California, that might mean earthquake, flood, fire, or tsunami information, depending on the exact spot. A city name alone is usually too broad.

Cal OES MyHazards is a helpful first look because it lets you search by address, city, zip code, or map location. The tool then shows hazard information near that location and gives preparedness steps tied to the layers it finds.

Use it early when you are moving, buying, renting, or planning an emergency kit. Then keep the limit in view: Cal OES calls the site general-purpose information. For an official zone boundary, parcel decision, real-estate disclosure, permit, insurance question, or evacuation order, use the exact map and agency responsible for that decision. MyHazards is the doorway, not the final ruling.
