Description

Plate boundary deformations, involving (a) surface velocities, (b) shear strains, and (c) mean strains, quantified here for theSan Andreas system by geodetic measurements, provide a framework for stress accumulation and release, but the overall driving process and resulting earthquake stresses are not well understood.
