Some physical properties of the Burridge-Knopoff model
The dynamics of the discrete Burridge-Knopoff model, initially presented for earthquake rupture, is analyzed here as a function of the main physical parameters. This discrete array of massive spring-connected ...

Characterization of Fault Roughness at Various Scales: Implications of Three-Dimensional High Resolution Topography Measurements
Accurate description of the topography of active fault surfaces represents an important geophysical issue because this topography is strongly related to the stress distribution along fault planes, and therefor...

The long precursory phase of most large interplate earthquakes
Foreshocks precede some—but not all—earthquakes. Analysis of all earthquakes larger than magnitude 6.5 that occurred between 1999 and 2011 shows that earthquakes at plate boundaries are often preceded by incre...

A Stochastic Study of Flow Anisotropy and Channelling in Open Rough Fractures
The quantification of fluid flow in rough fractures is of high interest for reservoir engineering, especially for deep geothermal applications. Herein, rough self-affine fractures are stochastically generated ...

Hydraulic Diffusivity of a Partially Open Rough Fracture
We investigate the impact of closing a fracture with rough surfaces on the fracture hydraulic diffusivity, which controls the spatiotemporal evolution of pore-pressure perturbations in geological formations, p...

Open AccessPermeability Evolution During Shear Zone Initiation in Low-Porosity Rocks
Using an innovative experimental set-up (Punch-Through Shear test), we initiated a shear zone (microfault) in Flechtingen sandstone and Odenwald granite under in situ reservoir conditions while monitoring perm...

Open AccessSynchronization of small-scale seismic clusters reveals large-scale plate deformation
It has long been observed that periods of intense seismic activity in a region alternate with periods of relative quiescence, but establishing whether or not this intermittency is driven by broad-scale physica...
