Abstract
Data from several tiltmeters and several creepmeters along the San Andreas fault in central California 30 km. south of Hollister were selected to investigate tilt perturbations of minutes to hours duration. The distribution in space and time of short-period tilt events suggests that most are due to causes other than slip on the San Andreas fault, such as local strain release. However some creep-related tilt events have been observed. Dislocation models capable of reproducing the creep-related tilt events have been constructed to examine the relationship of the model parameters, including source-station geometry and displacement time history, to the details of the tilt waveforms. These models suggest that at least some creep events of short duration are associated with finite size slip zones of shallow depth.
