Speaker: Peter Gold

"Tectonic Geomorphology and Active Faulting in Northern Baja California, Mexico"


Efforts to unravel the geologic slip histories of faults within the southern San Andreas Fault system have largely overlooked active faults in northern Baja California. However, offset landforms along the Agua Blanca Fault record evidence for dozens of earthquakes over the Holocene, and the 1892 Laguna Salada, 1956 San Miguel, and 2010 El Mayor-Cucapah surface rupturing earthquakes serve as reminders that this part of the plate boundary system is capable of producing potentially damaging seismicity. In recognition of this fact, new geochronologic methods, increasingly complex paleoseismic excavations, and high-resolution topography from lidar and photogrammetry, all methods that have long benefitted slip rate and rupture timing estimates for faults north of the border, are now being applied to active faults south of the border as well. While focusing primarily on the Agua Blanca Fault, this talk will explore tectonic geomorphology along active faults in northern Baja California, review early studies and existing data, and describe new and ongoing efforts to constrain the geologic slip histories of faults in this region.

Peter Gold is a Ph.D. candidate in geology at the University of Texas, Austin. For his doctoral research he uses lidar, field observations and quantitative geochronology to measure geologic fault slip rates with the end goal of understanding strain partitioning between parallel active faults within the southern San Andreas Fault system in southern California and northern Mexico. He has worked extensively in the western US along the Dixie Valley Fault and the southern San Andreas Fault in Coachella Valley and in northern Mexico along the Agua Blanca Fault and 2010 El Mayor-Cucapah rupture. He completed his B.S. and M.S. in geology at the University of California, Davis, where he used terrestrial lidar and 3D visualization systems to quantify uncertainties in measurements commonly made along fault scarps immediately following surface ruptures.
