The slip deficit on the North Anatolian Fault (Turkey) in the Marmara Sea: insights from paleoseismicity, seismicity and geodetic data
M. Meghraoui, Renaud Toussaint, M. Aksoy
The North Anatolian Fault experienced large earthquakes with 250-400 years recurrence time. In the Marmara Sea region, the 1999 (Mw = 7.4) and the 1912 (Mw = 7.4) earthquake ruptur…
Relative rates of fluid advection, elemental diffusion and replacement govern reaction front patterns
Daniel Koehn, Sandra Piazolo, Nicolas Beaudoin +4
Replacement reactions during fluid infiltration into porous media, rocks and buildings are known to have important implications for reservoir development, ore formation as well as…
Frictional anisotropy of 3D-printed fault surfaces
Tom Vincent-Dospital, Alain Steyer, François Renard +1
The surface morphology of faults controls the spatial anisotropy of their frictional properties, and hence their mechanical stability. Such anisotropy is only rarely studied in sei…
Stylolites: A review
Renaud Toussaint, E. Aharonov, D. Koehn +5
Stylolites are ubiquitous geo-patterns observed in rocks in the upper crust, from geological reservoirs in sedimentary rocks to deformation zones, in folds, faults, and shear zones…
Sinking during earthquakes: Critical acceleration criteria control drained soil liquefaction
Cécile Clément, Renaud Toussaint, Menka Stojanova +2
This article focuses on liquefaction of saturated granular soils, triggered by earthquakes. Liquefaction is definedhere as the transition from a rigid state, in which the granular…
Shake and sink: liquefaction without pressurization
Cécile Clément, Renaud Toussaint, Einat Aharanov
Soil liquefaction is a significant natural hazard associated with earthquakes. Some of its devastating effects include tilting and sinking of buildings and bridges, and destruction…
A General Criterion for Liquefaction in Granular Layers with Heterogeneous Pore Pressure
Liran Goren, Renaud Toussaint, Einat Aharonov +2
Fluid-saturated granular and porous layers can undergo liquefaction and lose their shear resistance when subjected to shear forcing. In geosystems, such a process can lead to sever…
Localization of Shear in Saturated Granular Media: Insights from a Multi-Scaled Granular-Fluid Model
Einat Aharonov, Liran Goren, David Sparks +1
The coupled mechanics of fluid-filled granular media controls the behavior of many natural systems such as saturated soils, fault gouge, and landslides. The grain motion and the fl…
Morphological analysis of stylolites for paleostress estimation in limestones surrounding the Andra Underground Research Laboratory site
Alexandra Rolland, Renaud Toussaint, Patrick Baud +2
We develop and test a methodology to infer paleostress from the morphology of stylolites within borehole cores. This non-destructive method is based on the analysis of the stylolit…
Growth of stylolite teeth patterns depends on normal stress and finite compaction
Daniel Koehn, François Renard, Renaud Toussaint +1
Stylolites are spectacular rough dissolution surfaces that are found in many rock types. Despite many studies, their genesis is still debated, particularly the time scales of their…
Hydrothermal coupling in a rough fracture
Amélie Neuville, Renaud Toussaint, Jean Schmittbuhl
Heat exchange during laminar flow is studied at the fracture scale on the basis of the Stokes equation. We used a synthetic aperture model (a self-affine model) that has been shown…
