Fault slip rates & paleoseismology within the southern San Andreas Fault System
Offset geomorphic features along the San Andreas fault in southern California and Baja California in Mexico record the fault’s rate of motion averaged over the past 2,000-150,000 years. We use a range of geomorphic analyses and Quaternary dating techniques to track the average rate of slip over different timescales as well as the earthquake history and recurrence interval over the Holocene.

Pleistocene to recent incision rates for the Rio Grande Gorge, New Mexico, USA
Terraces developed along the Rio Grande del Norte in northern New Mexico provide unique insight into the geomorphic evolution of this youthful river gorge. We are using detailed geomorphic mapping along with cosmogenic 3He dating to quantify incision rates and relate them to climatic and tectonic forcings.
