Single-Well Pore Pressure Preconditioning for Enhanced Geothermal System Stimulation
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, Barnaby Padraig Fryer
The stress state is an important parameter in terms of both earthquake nucleation and rupture. Here, a new stimulation technique is proposed for Enhanced Geothermal Systems (EGSs), which have previously been burdened with a number of high-profile incidence ...
AMER GEOPHYSICAL UNION2023Influence of Viscous Lubricant on Nucleation and Propagation of Frictional Ruptures
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Federica Paglialunga
Fluids are pervasive in the Earth's crust and saturate fractures and faults. The combination of fluids and gouge layers developing along faults can generate fluids of different viscosities. Such viscous fluids were found to influence the reactivation, fric ...
AMER GEOPHYSICAL UNION2023Long-term triggered seismicity on the Mosha fault by Damavand volcano, Iran: Implications on the seismic hazard of Tehran metropolis
The seismic history of the Mosha fault, the largest and most active fault of Eastern Tehran metropolis, and its relation to the Damavand active volcano, the highest mountain in the Middle East, is investigated. We deduce that the central Mosha, near the Da ...
2022Fault roughness’s influence on experimental fault mechanical behavior
Brice Tanguy Alphonse Lecampion, Marie Estelle Solange Violay, Barnaby Padraig Fryer, Seyyedmaalek Momeni, François Xavier Thibault Passelègue, Carolina Giorgetti
Fault slip behavior and earthquake nucleation are often framed within the context of velocity-dependent friction, ranging from velocity-strengthening to velocity-weakening behavior. Previous studies have shown that fault roughness controls the fault slip b ...
2022cRacklet: a spectral boundary integral method library for interfacial rupture simulation
Jean-François Molinari, Thibault Didier Roch, Fabian Barras
The study of dynamically propagating rupture along interfaces is of prime importance in various fields and system sizes, including tribology (nm to m), engineering (mm to m) and geophysics (m to km) (Armstrong-Hélouvry et al., 1994; Ben-Zion, 2008; Vanossi ...
2022Earthquake Nucleation along Faults with Heterogeneous Weakening Rate
Jean-François Molinari, Marie Estelle Solange Violay, Thibault Didier Roch, Mathias Alexandre David Lebihain
The transition from quasi-static slip growth to dynamic rupture propagation constitutes one possible scenario to describe earthquake nucleation. If this transition is rather well understood for homogeneous faults, how the friction properties of multiscale ...
2021On the scaling between precursory moment release and earthquake magnitude: Insights from the laboratory
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta
Recent seismological observations highlighted that both aseismic silent slip and/or foreshock sequences can precede large earthquake ruptures (Tohoku-Oki, 2011, Mw 9.0 (Kato et al., 2012); Iquique, 2014, Mw 8.1 (Ruiz et al, 2014; Socquet et al., 2017); Ill ...
2020Mechanical behaviour of fluid lubricated faults during earthquake nucleation and propagation
The need for new forms of energy, and in particular the need for renewable and clean ones, led to develompment of Enanched Geothermal Systems, where the well designed stimulation of a geothermal reservoir is the key parameter for the safe development of th ...
EPFL2020Effect of Fluid Viscosity on Earthquake Nucleation
Marie Estelle Solange Violay, Chiara Cornelio
Injection of fluids in geo-reservoirs can reduce the effective stresses at depth, lubricating the nearby faults, promoting slip and, potentially, earthquakes. High-viscous fluids are often used during hydraulic fracturing and production phases in geo-reser ...
2020Can Precursory Moment Release Scale With Earthquake Magnitude? A View From the Laboratory
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta
Today, earthquake precursors remain debated. While precursory slow slip is an important feature of earthquake nucleation, foreshock sequences are not always observed, and their temporal evolution remains poorly constrained. We report on laboratory earthqua ...
