McFarland, F.S., Lienkaemper, J.J., Caskey, S.J., and Elliott, A.J., 2017, Data from Theodolite Measurements of Creep Rates on San Francisco Bay Region Faults, California (ver. 2.2, July 2023): U.S. Geological Survey data release, https://doi.org/10.5066/F76W9896.

Summary

The data comprise an archive of repeated surveyed measurements to monitor surface fault creep (a form of gradual tectonic movement) occurring along active faults in the San Francisco Bay region for use by the scientific research community. Additional description of these data and the methods used to collect them is provided at: https://pubs.usgs.gov/of/2009/1119/. The primary data are angle measurements surveyed using an electronic theodolite on about ninety alignment arrays that cross the region's major faults, which enables detection of any significant rate changes over time from long-term rates of aseismic fault displacement. These primary measurement data, and resulting long-term average creep rates of each site, are updated annually [...]

Purpose

Our purpose is to annually update our creep-data archive on San Francisco Bay region active faults for use by the scientific research community. Additional description of these data and the methods used to collect them is provided at: https://pubs.usgs.gov/of/2009/1119/ The scientific motivation is to understand the proportion of tectonic slip that occurs aseismically (i.e., by fault creep), in order to estimate the seismic hazard represented by the five branches of the San Andreas fault system (see the larger work citation, Lienkaemper and others (2014) above).
