How do I find the nearest fault to a property or specific location?
If you are looking for faults in California use: How Close to a Fault Do You Live? (Bay Area Earthquake Alliance)
For faults in California and the rest of the United States (as well as the latest earthquakes) use the Latest Earthquakes Map:
- click on the "Basemaps and Overlays" icon in the upper right corner of the map.
- check the box for "U.S. Faults".
- mouse-over each fault to get a pop-up window with the name of the fault.
The Quaternary Fault and Fold Database has an interactive map for viewing faults within the United States and a fault database.
The Information by Region section of the Earthquake Hazards Program website has links to many resources for faults and earthquakes for each state in the United States.

Why are there so many earthquakes and faults in the Western United States? Why are there so many earthquakes and faults in the Western United States?
This region of the United States has been tectonically active since the supercontinent Pangea broke up roughly 200 million years ago, and in large part because it is close to the western boundary of the North American plate. Since the formation of the San Andreas Fault system 25-30 million years ago, the juxtaposition of the Pacific and North American plates has formed many faults in California...
Why are there so many faults in the Quaternary Faults Database with the same name? Why are there so many faults in the Quaternary Faults Database with the same name?
Many faults are mapped as individual segments across an area. These fault segments are given a different value for name, number, code, or dip direction and so in the database each segment occurs as its own unique entity. For example, the San Andreas Fault has several fault segments, from letters a to h, and fault segment 1h has segments with age of last fault movement from historic (<150 years) to...
