1 Introduction. The San Andreas Fault System in Northern California consists of three subparallel strands, the San Andreas (SAF), Maacama (MF), and Bartlett Springs (BSF) (Figure 1).While relatively less is known about the deformation rates associated with the MF and BSF than for their southeastward extensions in the San …Calaveras Fault creep in downtown Hollister in April 2009.
