Marie Violay is a researcher specializing in rock mechanics, rock physics, fault mechanics, and experimental rock deformation. Her work explores the mechanical behavior and failure modes of volcanic rocks, the brittle-ductile transition of basalt under oceanic crust conditions, and the role of effective stress in earthquake dynamics. She investigates fault reactivation during fluid pressure oscillations, porosity evolution in continental crust, and the impact of water on frictional behavior during earthquakes. Her research also examines dynamic weakening during seismic events, fluid thermodynamics, and the geochemical signatures of co-seismic processes. Violay's studies contribute to understanding deep hydro-geothermal circulation, fault stability, and the thermo-mechanical pressurization of experimental faults.
