Mechanical behaviour of fluid-lubricated faults

Marie Estelle Solange Violay, Chiara Cornelio

Fluids are pervasive in fault zones cutting the Earth's crust; however, the effect of fluid viscosity on fault mechanics is mainly conjectured by theoretical models. We present friction experiments performed on both dry and fluid-permeated silicate and car ...

Unstable Slip Pulses and Earthquake Nucleation as a Nonequilibrium First-Order Phase Transition

Jean-François Molinari, Fabian Barras

The onset of rapid slip along initially quiescent frictional interfaces, the process of “earthquake nucleation,” and dissipative spatiotemporal slippage dynamics play important roles in a broad range of physical systems. Here we first show that interfaces ...

Effect of fluid viscosity on fault frictional behaviour

Marie Estelle Solange Violay, Chiara Cornelio

Understanding fluids viscosity effects on fault dynamics can shed light on the induced seismicity in engineering reservoirs where fluids with viscosity ranking from 1mPa s-1 to 1000 mPa s-1 are also injected during hydraulic fracturing process in order to ...

Fast-moving dislocations trigger flash weakening in carbonate-bearing faults during earthquakes

Marie Estelle Solange Violay, Andrea Cavallo

Rupture fronts can cause fault displacement, reaching speeds up to several ms(-1) within a few milliseconds, at any distance away from the earthquake nucleation area. In the case of silicate-bearing rocks the abrupt slip acceleration results in melting at ...

Effect of water on the frictional behaviour of cohesive rocks during earthquakes

Marie Estelle Solange Violay, Andrea Cavallo

Fluid-rock interactions can control earthquake nucleation and the evolution of earthquake sequences. Experimental studies of fault frictional properties in the presence of fluid can provide unique insights into these interactions. We report the first resul ...

Interfaces: How the Rupture Speed of Slip Fronts is Related to the Deformation Energy

Jean-François Molinari, David Simon Kammer, Vladislav Yastrebov

The transition from sticking to sliding of a frictional interface does not happen uniformly. The shear resistance of the interface is usually reached at a single point from which an interface rupture starts to propagate (Rubinstein et al., 2004). The repet ...

Connectivity of Phases and Growth Mechanisms in Peritectic Alloys Solidified at Low Speed: an X-Ray Tomography Study of Cu-Sn

Michel Rappaz, André Phillion, Jonas Valloton, Marco Stampanoni

The variety of microstructures that form at low solidification speed in peritectic alloys, bands, and islands, or even coupled (or cooperative) growth of the primary alpha and peritectic beta phases, have been previously explained by nucleation-growth mech ...
