Présentation

How do faults release the stresses they have accumulated over tens or hundreds of years? This is the main question that has motivated my research. I have used seismological and geodetic observations combined with modelling approaches to infer how faults slip at depth. In particular, I have focused on the pre-seismic phase (i.e. how earthquakes start), the co-seismic phase (i.e. how earthquakes propagate and stop), and the post-seismic phase (i.e. how faults continue to relax after rupture).
