Job description

To mitigate seismic risks from subsurface exploitation sites (geothermal energy, subsurface CO2, H2 storage), accurate seismic hazard assessment (SHA) is a necessity. In regions without historical earthquakes, conventional ground motion models cannot be locally calibrated and thus suffer from large uncertainty, rendering them unreliable for the seismic risk assessment of future subsurface activities. The SHAWave project – a collaboration between various Dutch universities and research institutes – will take a new and innovative approach to conducting probabilistic seismic hazard assessment. This approach combines novel computational modelling techniques, based on waveform simulations, with advanced data calibration and risk quantification techniques.

You will analyse the role of subsurface structure on ground motion distribution through a full elastic finite element seismic wave simulation. To fully appreciate the effect of directional propagation and interaction you will include the subsurface topography and a realistic velocity model. The attenuation in the model, for both bedrock and sediments, will be based on amplitude matching between our simulations and actual observations for the modelled earthquake. You will use SALVUS for our simulations, a code developed for simulating seismic wave propagation based on the principles of SEM.

You will be defining the optimal resolution for such modelling based on existing subsurface models and earthquake recordings at the surface and in boreholes (till 200m depth), you will assess the subsurface structure related to amplification and directional effects, and you will evaluate the near-surface sediment effect based on analysis of your modelled waveforms in comparison to actual recorded waveforms in boreholes and at the surface. You will also prepare a modelling-based predictive probable seismic hazard map with an initial focus on the Groningen area, a region in the Netherlands with human-induced earthquakes due to gas exploitation, and finally, you will extend this new approach for seismic hazard analysis to new exploitation sites in the Netherlands for which no earthquakes have been recorded yet.

Your project will be embedded in the Applied Earth Sciences department at the Faculty for Geo-Information Science and Earth Observation at the University of Twente. You will work together with the partners in the SHAWave project to ensure that the developed model is successfully integrated. You will have short stays with partners in the project, particularly you will work together with the Energy Technology section at the Department of Mechanical Engineering of the Eindhoven University of Technology (TU/e).
