This PhD thesis is dedicated to the study of injection induced fault reactivation using a coupled hydro-mechanical rate and state modelof a fault. Even though the principal mechanisms behind induced fault reactivation are well known, different aspects are not yet fully explored, nor understood. In the first part of this thesis, we explore successively the role of the injection protocol (in particular, injection maximum pressure and injection pressure rate), and the fault frictional parameters on the rate of induced events and their magnitude content, for different heterogeneous 2-D fault configurations. We first point out a temporal correlation between the seismicity rate and the pore pressure rate governing the fault. We then show a depend...
