Résumé

• We use template matching, double-difference relocations, and moment magnitudes to create a high-resolution catalog of the Maurienne swarm • At least two conjugate fault systems with opposite dip directions were reactivated during the swarm • The complex migration of seismicity suggests that the swarm may be driven both by pore-pressure diffusion and by earthquake interactions
