Segments of the San Andreas Fault

• Historically, the San Andreas has been divided up into individual fault segments that range from tens to hundreds of kilometers.

• These include the Big Bend, Coachella, & Parkfield fault segments. Several segments of the San Andreas fault in Southern California.

Segments of the San Andreas Fault• The San Andreas can be divided

up into three larger segments as well.

• Southern, Central, and Northern.

• Complex fault geometries of the Southern and Northern allow for large earthquakes (Li and Liu, 2006).

• Central segment is dominated by aseismic creep.
