| The overall goal of my research is to integrate the analysis
of geological subsurface data (by studying seismic reflection
profiles and seismology in seismically active regions), field
geology observations (by investigating ancient exhumed faults
that represent analogues of seismically active structures today)
and results from rock deformation experiments (by conducting
permeability and friction experiments) in order to better understand
the mechanics of faulting and earthquakes. |

Frictional reactivation and earthquakes
Control of fault reactivation theory on mainshocks and aftershock
sequences. Fluid involvement in seismic rupture nucleation and
aftershocks triggering. Low-angle normal faults and microseismicity.
The role of inherited structures in seismic rupture nucleation
and arrest. |
| |
Fault zone processes
Fault zone structure inferred from ancient exhumed faults. Fluid
assisted dissolution-precipitation processes and the development
of phyllosilicates within fault zones. Cataclastic processes
and localization along fault zones within the sedimentary cover.
Fluid overpressure and hydrofractures. |
| |
Rock deformation experiments.
Physical properties of anhydrites, dolostones and gypsum. Frictional
behaviour of phyllosilicates (solid foliates samples vs. powdered
material), anhydrites and dolostones and related microstructures. |
