Fault Slip Rates San Andreas, Macaama, Bartlett Springs Faults

Shallow and deep fault slip rates inferred for the San Andreas fault, Macaama fault, and Bartlett Springs fault. Only the deep slip rate is shown for the SAF. The long-term slip rate of each fault is ideally its deep slip rate; the shallow portion of each faults catches up to the (generally higher) velocity of the deeper portion episodically, i.e. during earthquakes. The higher the shallow slip rate, the more the fault is creeping, hence the lower the expected size of earthquakes.
