Rupture History of the San Andreas Fault in the Carrizo Plain prior to 1300 A.D.
It is important to determine variability in time between earthquakes to constrain uncertainty in probabilistic calculations of rupture potential. Results from our field work since 2005 at the Bidart site in the Carrizo Plain and new radiocarbon dates from archival samples collected for Grant’s 1993 dissertation reveal evidence of six ruptures of the San Andreas fault (SAF) between 1345 and 1857 AD.
