A handful of faults in California manifest some form of surface creep: afterslip, episodic slip, steady slip, or triggered slip. Creep can be considered a proxy for shear strain applied to a fault, although its rate is sensitive also to fault-normal stresses, variations in the frictional properties of the near-surface fault, and in some locations to variations in near-surface moisture content. Creepmeters afford a view of fault activity with micron precision, at rates of up to 5 mm/minute, though creep rates on most California faults are typically less than several millimeters per year. This article summarizes the current status of...
