In this study we compare the effective thickness of the locked zone derived from seismicity with the thickness derived from geodesy to quantitatively measure the similarities and differences in the two approaches along the SAFS (San Andreas Fault System).

Here are presented systematic measurements of the frictional properties and composition of the San Andreas Fault at 2.7 km depth, including the wall rock and active fault. We nd that the faultis weak relative to the surrounding rock and that the fault rock ...

Three-dimensional numerical models are needed to investigate the role of nonvertical strike-slip fault segments on the deformation within restraining bends. Numerical models simulate geologic deformation of two alternative three-dimensional present-day configurations ...

Seismic velocity changes and nonvolcanic tremor activity in the Parkfield area in California reveal that large earthquakes induce long-term perturbations of crustal properties in the San Andreas fault zone.

Here are presented high-resolution measurements of interseismic deformation across the southern San Andreas fault system using a well-populated catalog of space-borne Synthetic Aperture Radar data.

<p>We determine the long-term slip rate of the southern San Andreas Fault in the southeastern Indio Hills using 10Be and 26Al isotopes to date an offset alluvial fan surface.</p>

The method using the propagation of acoustic body waves within the stress modified areas around a vertical borehole has been applied to the granitic formation penetrated by the SAFOD Pilot hole near the San Andreas Fault trace. This method allows to investigate ...

In this paper are presented new continuous and differential global positioning system (GPS) measurements of recent slip rates and 30 yr alignment-array offsets from the central creeping segment of the San Andreas fault yield a maximum right-lateral slip rate ...

The San Andreas fault in California has long been thought to be far weaker than given by the Anderson-Byerlee state because of the lack of a heat-flow anomaly adjacent to the fault as predicted by a steady-state conductive model of frictional heating. Here ...

<p>An earthquake alters the shear and normal stress on surrounding faults. New evidence strengthens the hypothesis that such small, sudden stress changes cause large changes in seismicity rate. Rates climb where the stress increases (aftershocks) and fall ...
