Data from Theodolite Measurements of Creep Rates on San Francisco Bay Region Faults, California (ver. 2.2, July 2023)
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 at most sites.
