Rupture history of the San Andreas Fault in the Carrizo Plain

Investigators

Summary

The San Andreas fault is an important natural laboratory for understanding fault rupture and the patterns of large earthquakes. It is also a major threat to the health and safety of Californians. The goal of this project is to investigate the rupture history of the San Andreas fault in the Carrizo Plain, a section that has been hypothesized to rupture only in the largest earthquakes. We have focused on the Bidart fan site because previous work has shown that it has the potential to yield a record of approximately 10 earthquakes spanning almost 3000 years for testing models of fault behavior and assessing seismic hazard.
