Initial phase of field mapping along the trace of the surface rupture S of 178 is now complete. I was in the field with Rich Koehler (UNR), Ian Pierce (UNR), Jayne Bormann (UNR) and Alana Williams (ASU) during my first trip. I joined James Dolan (USC) and Alex Hatem (now USGS) for my second trip. My student and SCEC intern Sena Padilla and I followed and hunted several fault traces during my 3rd and last visit to Ridgecrest.

Here is the link for the GEER Ridgecrest Report.

Nick Inserra successfully presented and defended his thesis on July 1, 2019. His thesis title is "Late Holocene Rupture History of the South-Central San Andreas Fault at Van Matre Ranch, California".

Congratulations, Nick! I am proud that you were my first M.S. student.

Eastern Peninsular Ranges Mylonite Zone is an ideal analog for the deep crustal shear zone associated with the Coachella Valley segment of the SAF system. The purpose of our study is to directly observe and sample this analog shear zone to place geologic constraints on the rheology of deep-crustal shear zones for direct incorporation into the SCEC Community Rheology Model. Can't wait to start on this new project with Dr. Elena Miranda and Dr. Joshua Schwartz from CSUN.

I will be back at this beautiful sag at the southern end of the Carrizo National Monument and nearby offset channels to do collaborative investigation with Prof. Matt Kirby. Stay tuned to find out what we can learn from integrated paleoclimate and paleoseismic investigations.
