## Hamiltonian Monte Carlo to Characterize Induced Earthquakes

### Application to a M_{L} 3.4 Event in the Groningen Gas Field and the Role of Prior

The Hamiltonian Monte Carlo algorithm is known to be highly efficient when sampling high-dimensional model spaces due to Hamilton's equations guiding the sampling process. For weakly non-linear problems, linearizing the forward problem enhances this efficiency. This study inte ...

## Probabilistic centroid moment tensor inversions using geologically constrained priors

### Application to induced earthquakes in the Groningen gas field, the Netherlands

We use the Hamiltonian Monte Carlo (HMC) algorithm to estimate the posterior probability distribution of a number of earthquake source parameters. This distribution describes the probability of these parameters attaining a specific set of values. The efficiency of the HMC algo ...

## Linking geomechanical simulation of induced seismicity to surface seismic observations

### Simulated finite fault rupture to moment tensor inversion

We present a probabilistic scheme to invert for hypocenters and moment tensors (MTs) of induced seismic events in 2D heterogeneous media. Our scheme is based on a variant of the Hamiltonian Monte Carlo scheme that uses the linearization of a misfit function. This algorithm, ho ...
