Seth Saltiel | Department of Geological Sciences and Engineering
I studied physics and energy and resources as an undergraduate and geophysics as a graduate student at the University of California at Berkeley and the Lawrence Berkeley National Lab, with a brief stop between two work in geothermal energy at the National Renewable Energy Laboratory in Golden, Colorado. After a one-year visit to the Department of Geophysics at the University of Chile in Santiago, I was a post-doctoral researcher at the Rock and Ice Mechanics Laboratory of the Lamont Doherty Earth Observatory at Columbia University. . I am now starting a research professor position at the Nevada Seismological Lab here at the University of Nevada, Reno in 2022.
As an experimental geophysicist, my research interests focus on the frictional and seismic behavior of geological interfaces under shear. These boundaries control dynamic earth processes of societal importance at many scales.
My work includes applications for:
- Tectonic faults that control continental-scale deformation and earthquakes
- Glacier beds that control the flow and mass balance of ice caps and future sea level changes
- Fractures that control permeability and induced seismicity in underground energy, water and waste reservoirs
- Landslide, rocky slope and avalanche rupture surface which control the evolution of the relief and the local dangers.
My work sheds light on our understanding of dynamic behavior and geophysical properties, as well as their dependence on changing conditions. I perform lab-scale measurements, both to better constrain the underlying physics to exciting new observations and to improve the constitutive relationships to represent these processes in large-scale models. I am also interested in connecting experimental developments with new field techniques to shed light on the underlying mechanics of these key geological problems. Better connections between laboratory-scale knowledge and field observations, as well as between scientific disciplines, are essential to predict and manage our interaction with important Earth systems.
