Southern Sierra Nevada fault zone, Haiwee Reservoir section (Class A) No. 65b Last Review Date: 1995-10-01This suggests that active faults in southern California are weak. The maximum principal stress axis near the San Andreas Fault is often at ∼50° to the fault strike, indicating that the shear stress on the fault is comparable to the deviatoric stress. The San Andreas in southern California may therefore be a weak fault in a low-strength crust.
