  abstract = {{W}e implement a {C}oulomb rate-and-state approach to explore the nonlinear relation between stressing rate and seismicity rate in the {G}roningen gas field. {C}oulomb stress rates are calculated, taking into account the 3-{D} structural complexity of the field and including the poroelastic effect of the differential compaction due to fault offsets. {T}he spatiotemporal evolution of the {G}roningen seismicity must be attributed to a combination of both (i) spatial variability in the induced stressing rate history and (ii) spatial heterogeneities in the rate-and-state model parameters. {F}ocusing on two subareas of the {G}roningen field where the observed event rates are very contrasted even though the modeled seismicity rates are of similar magnitudes, we show that the rate-and-state model parameters are spatially heterogeneous. {F}or these two subareas, the very low background seismicity rate of the {G}roningen gas field can explain the long delay in the seismicity response relative to the onset of reservoir depletion. {T}he characteristic periods of stress perturbations, due to gas production fluctuations, are much shorter than the inferred intrinsic time delay of the earthquake nucleation process. {I}n this regime the modeled seismicity rate is in phase with the stress changes. {H}owever, since the start of production and for two subareas of our analysis, the {G}roningen fault system is unsteady and it is gradually becoming more sensitive to the stressing rate.},
