The fault-creep-monitoring project at San Francisco State University (SFSU) was created by Jon Galehouse in 1979, and has been funded from its beginning by the U.S. Geological Survey's National Earthquake Hazards Reduction Program (NEHRP). Since 1979, the project has produced an invaluable and unique data set (e.g., Galehouse, 2002; Galehouse and Lienkaemper, 2003) and has provided reliable part-time research assistantships for more than two dozen SFSU students. We are currently monitoring creep at about 39 sites along active strike-slip faults in the San Francisco Bay region and northern California including: the San Andreas, Calaveras, Concord-Green Valley, Greenville, San Gregorio, Rodgers Creek, Maacama, Hunting Creek, and Bartlett Springs faults. We typically survey sites on creeping fault segments two times each year, and non-creeping sites at least once each. We maintain an intensive monitoring program at 32 creeping sites on the Hayward fault in conjunction with J. Lienkaemper of the US Geological Survey (e.g., Lienkaemper et al., 2001). If you have questions about the project, please contact John Caskey, Associate Professor at San Francisco State University (firstname.lastname@example.org), who currently runs the program.
This research has been supported by numerous U.S. Geological Survey (USGS) Grants since the project was created by Jon Galehouse in 1979. The project is currently funded by USGS National Earthquake Hazard Reduction Program (NEHRP) Cooperative Agreement G10AC00139. The accomplishments of this project would not be possible without the involvement of the many student research assistants who have worked on the project over the years (see Project Personnel page).
