one is the San Andreas Fault in California.
OK!over 99 active faults!
Normal faults
Deep furrows in the ground or ocean floor are faults. San Andreas fault in California is a prime example, having displacement hundreds of kilometers long. Two kinds of faults are dip-slip faults and strike-slip faults.
There are many faults throughout the US. The one that is most widely know is the San Andreas Fault in California and other Western States.
Fault zones are areas where there are many interconnected faults.
Geological faults are planar fractures. More information can be found on sites such as Wikipedia, as well as the California Geological Survey website.
