Using a boundary element method together with a fault-propagation criterion based on the maximum distortional strain energy density, we explored the possibility that the big bend along the San Andreas fault may have perturbed and amplified the stress field around the bend, thereby inducing a zone of shearing in a north-northwest orientation at the southern end of the bend. The simulated fault-propagation path agrees well with the data and sheds light on the origin and nature of the seismicity north and east of the big bend of the San Andreas. This content is PDF only.
