The ultimate goal of the ESM project is to develop, evaluate and apply a world-leading Earth system modelling infrastructure - leading into an Earth System Simulator - to provide solutions to grand challenges faced by the Earth and environmental sciences. Our contribution is to model the large scale thermo-mechanical processes that control the contemporary deformation pattern in central Western Europe on scales from 10 km 1000 km, and to conceptually link the result into a workflow of physics-based probabilistic seismic hazard assessment for low strain areas. The classical probabilistic seismic hazard assessment (PSHA) is based on seismic event catalogues and does not yet consider physical processes of stress and strain accumulation during the seismic cycle. In particular for low strain intraplate regions this approach is under controversial debate in past years (e.g. Calais et al., 2016).

The model will integrate a wide range of data such as gravity, seismological catalogues, tectonic stress, temperature and GPS observations. Furthermore, the model results should be linked to a complementary ESM PhD position at the GFZ Potsdam (Section 6.1 – Basin Modelling) that is modelling thermo-hydro-mechanical (THM) processes at basin and reservoir scale. The envisioned link is that the large scale model should deliver initial and boundary conditions for the THM simulations and both models are expected to establish jointly a workflow to quantify the key model uncertainties (e.g. Ziegler et al., 2016). We will validate the model against a wide range of geo-data sets (in particular stress data and GPS observations) and develop in the final stage of the project a concept how to link the model results in the classical PSHA approach.
