3D geomechanical modelling of induced seismicity: finite source wavefield simulation to moment tensor inversion

Geomechanical modelling is generally used to simulate the nucleation of induce d earthquakes in, for instance the Groningen gas field. We apply quasi static simulation to investigate the stress changes from gas production. When a fault reaches a critical state, dynamic simulation provides information on the dynamic rupture during ea rthqu ake...

3D geomechanical modelling of induced seismicity: Simulated finite-source to moment tensor inversion

An efficient probabilistic workflow for estimating induced earthquake parameters in 3D heterogeneous media

We present an efficient probabilistic workflow for the estimation of source parameters of induced seismic events in three-dimensional heterogeneous media. Our workflow exploits a linearized variant of the Hamiltonian Monte Carlo (HMC) algorithm. Compared to traditional Markov chain Monte Carlo (MCMC) algorithms, HMC is highly efficient in...
