PhD Position on Stress and strain accumulation in stable part of Western Europe

05.07.2017 - GFZ German Research Centre for Geosciences, Potsdam (Germany)

Section 2.6 "Seismic Hazard and Stress Field" of the GFZ German Research Centre for Geosciences in Potsdam offers a PhD Position on "Stress and strain accumulation in stable part of western Europe: Implications for probabilistic seismic hazard assessment".

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 few years (e.g. Calais et al., 2016, http://dx.doi.org/10.1002/2016GL070815).

Thus, the overall goal is to model the large scale thermo-mechanical processes that control the contemporary deformation and stress pattern in central Western Europe on scales between 1000 and 100 km and to link the result into a workflow of physics-based probabilistic seismic hazard assessment for low strain areas. 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 PhD position at the GFZ Potsdam (section 6.1 Basin Modelling) that is modelling thermo-hydro-mechanical (THM) processes at reservoir scale.

The envisioned link is that the large scale model should deliver initial and boundary conditions for the THM simulations. Both models are expected to establish jointly a workflow in order to quantify the key uncertain-ties of the model (e.g. Ziegler et al., http://dx.doi.org/10.5194/se-7-1365-2016).
