The National Science Foundation awarded a $796,676 project grant to the University of Maryland, College Park to support research investigating the mechanisms enabling high pore fluid pressure to facilitate slow faulting. Funded through the Geosciences program (CFDA 47.050), the three-year award will advance understanding of the role elevated fluid pressures play in stabilizing fault propagation and decelerating frictional slip along pre-existing faults. Researchers will conduct fracture and friction experiments using dynamic microtomography to characterize in real-time the microstructural evolution and resulting spatial and temporal distributions of permeability, porosity, and pore shape under different drainage conditions during brittle failure. Varying pore fluid pressures and fault gouge materials will explore the mechanical link between high fluid pressures and slow slip behaviors. The project aims to elucidate dilatant hardening's role in transitions between stick-slip events and slow slip, and identify diagnostic fault geometry and off-fault damage features associated with slow faulting. Findings seek to improve comprehension of different fault instabilities and responsible mechanical processes.
