How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach

Henri Joseph François Gilles Leclère

Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...

Can 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 ...

From aseismic to seismic slip during fluid pressure oscillations on laboratory fault

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Carolina Giorgetti, Corentin Jean-Marie Rémi Noël

A rise in fluid pressure decreases the effective normal stress acting on faults, facilitating reactivation. Within the upper crust, fluid pressure cyclic perturbations are common. They can originate from natural causes such as oceanic tides, seasonal hydro ...

Induced seismicity in geologic carbon storage

Lyesse Laloui, Victor Vilarrasa Riano

Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock stress field and may induce (micro) ...

Experimental investigation on the deformation capacity of lap splices under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

Correct detailing and positioning of lap splices is essential in order to prevent premature failure of reinforced concrete structural members. Especially before the introduction of capacity design guidelines, lap splices were often placed in member regions ...

Fluid injection driven, a-seismic fracture growth with remote nucleation on heterogeneous fault

Brice Tanguy Alphonse Lecampion, Andreas Möri, Federico Ciardo

Induced (and triggered) seismicity following fluid injections at depth, is governed by pore pressure diffusion. Interestingly, recent studies yield unrealistically large values of diffusivity in order to explain the timing of the generated seismicity. We i ...

Behavior of iron-based Shape Memory Alloys under Cyclic Loading Histories

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Diego Isidoro Heredia Rosa, Masoud Motavalli, Alexander Riley Hartloper

Shape memory alloys (SMAs) have gained considerable attention in a broad range of engineering applications. In particular, iron-based SMAs (Fe-SMAs) have been recently developed and used as a cost-effect method for prestressed-strengthening of civil struct ...

Effect of dilatancy on the transition from aseismic to seismic slip due to fluid injection in a fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Aseismic crack growth upon activation of fault slip due to fluid injection may or may not lead to the nucleation of a dynamic rupture depending on in-situ conditions, frictional properties of the fault and the value of overpressure. In particular, a fault ...
