The National Science Foundation Division of Earth Sciences awarded the University of Utah $210,713 on January 1, 2026, under the Geosciences program (CFDA 47.050) to conduct experimental research assessing the roles of wear and roughness on dynamic fault friction. The project will advance earthquake physics through controlled laboratory experiments using a specialized deformation apparatus to explore mechanisms regulating fault friction during seismic slip. The work includes experimental validation of physics-based constitutive equations describing frictional behavior of geologic materials under earthquake-like conditions, with independently controlled and elevated pore pressure, confining pressure, and normal stress at fixed slip rate. Results will inform the development and modification of earthquake rupture models to support hazard and risk mitigation worldwide. Performance occurs at the University of Utah in Salt Lake City, Utah, through May 31, 2027. No sub-awards are planned.
