Map showing Quaternary faults in the western U.S. and Pacific Ocean. Note that most faults that can affect residents are either onshore or just offshore. The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained.
This feature layer, utilizing data from the U.S. Geological Survey's Earthquake Hazards Program, displays known faults and folds in the U.S.
Interactive Quaternary faults map. (Public domain.) Download Data: This database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Ma).
The most prominent faults in each state are usually shown on a state's geologic map as black lines. However, many faults are entirely beneath the surface and do not reach ground level. Therefore, these buried faults have no fault lines, and they are usually not shown on geologic maps.
This new-generation stress map of North America includes the first view of the style of faulting across the continent as well as more than 300 new measurements of the direction from which the greatest pressure occurs in the Earth’s crust.

These maps are used in determining building seismic codes, insurance rates, and other public decisions. The amount of shaking an earthquake produces at a particular place depends not only on the earthquake's size, but also local characteristics like the bedrock type and soil type.
Earthquake Faults and Folds in the USA. This feature layer, utilizing data from the U.S. Geological Survey's Earthquake Hazards Program, displays known faults and folds in the U.S.
An online map of faults ( Quaternary Fault and Fold Database of the United States ) that includes California is in the Faults section of the Earthquake Hazards Program website. Choose the Interactive Fault Map, or download KML files and GIS shapefiles from the links on the page.
