Robert D. Nason; Preliminary Instrumental Measurements of Fault Creep Slippage on the San Andreas Fault, California. Seismological Research Letters ; 40 (1): 7–10. doi: https://doi.org/10.1785/gssrl.40.1.7
Recent studies have delineated the occurrence of fault creep slippage on the San Andreas, Hayward, and Calaveras faults in central California. Preliminary instrumental measurements show that fault creep has different time character at different sites, being eventful at some places and continuous at others. Creep events measured at two sites indicate a creep propagation rate of of the order of 10 km/day.
