The San Andreas fault system in California is probably the best studied plate boundary zone in the world.  After recognition of the seismic hazard posed by the San Andreas fault following the destructive San Francisco earthquake in 1906, a wide variety of geological and geophysical tools have been applied to understand plate boundary deformation. This talk will cover the tectonic evolution of the plate boundary system over the past 30 million years and what we know about historical earthquakes such as the San Francisco earthquake. More recent work on the fault will also be discussed, including new data from a drill hole that pierced the San Andreas fault near Parkfield this past summer and some of the surprising new findings that have come out of this work.  


Dr. Titus teaches introduction to geology, tectonics, structural geology and geophysics. Her current research is focused on lithosphere and mantle dynamics, including using GPS to investigate the San Andreas fault in central California, and looking at strain gradients preserved in mantle shear zones in New Caledonia.
