Interplay between damage and friction weakening during earthquake initiation : from laboratory experiment to numerical modeling

Earthquake sliding occurs naturally in response to long-term deformation produced by plate tectonics ; they may also be triggered by human activities related to natural resource extraction that affect the stress field and damage the rocks. However, the way the damage of the medium and the cohesiveness of the damaged rocks control the slip behavior and the seismic patterns is not well understood.
