The famous San Andreas fault in California is an excellent place to understand the behavior of faults. Khoshmanesh and Shirzaei used high-resolution satellite measurements to track surface deformation along the central portion of the fault over two decades. Accurate modeling of the deformation requires shifts in the time scale of the fault's aseismic creeping behavior from yearly to decadal. The different modes of creep are important for assessing seismic hazard and may provide some clues about fault rupture.
