experienced by strike slip faults oriented in the direction of the
San Andreas Fault

(i) Due to all M > 6.5 earthquakes

(ii) Due to all M > 6.5 earthquakes and plate motion
(constrained using GPS data which in turn
has been corrected for all transient effects including postseismic
deformation following historic earthquakes)
