PhD position in physics-based modeling of fault reactivation and induced seismicity
The Swiss Seismological Service (SED, www.seismo.ethz.ch ) at the Department of Earth Sciences is the agency responsible for earthquakes monitoring. The SED conducts a broad range of fundamental and applied research in earthquake science and specifically in the field of induced seismicity risk and multi-risk. Within the framework of the project Precode/FEAR at the Bedretto Underground Laboratory for Geosciences and Geonergies (www.bedrettolab.ethz.ch ), we intend to further develop physics-based models to study fault reactivation.
The Bedretto Underground Laboratory for Geoscience and Geo-energies offers the outstanding opportunities to observe and analyse countless pico-earthquakes induced during stimulation or mine-by experiments under controlled and repeatable conditions. Using borehole-based multi-parameter arrays of sensors, we strive to model fluid-rock interactions, effects of tunnelling and other triggering mechanism related to fault reactivation and interpret the results in a multidisciplinary context.
With funding from the PRECODE "Progressive Excavation Damage zone evolution during and post mine-by tunneling" and the ERC Synergy project FEAR “Fault Activation and Earthquake Rupture”, we seek at analyzing the impact of tunnel construction on potential reactivation of fault zones and the associated changes in their hydraulic properties as well as modeling earthquake nucleation experiments at decameter scale. As part of a highly interdisciplinary team of scientists you will be involved in designing and modelling experiments on earthquake nucleation, propagation and termination (Contacts: Dr. Antonio Pio Rinaldi, Prof. S. Wiemer).
You will focus on using advanced numerical modeling tools (e.g. TOUGH-FLAC) to perform numerical simulation of fault reactivation at the scale fo the Bedretto Lab (tens to hundreds of meters) and upscaling to the scale of natural/induced seismicity. You will improve current numerical models by implementing theoretical advances in simulators, helping to build a bridge between the different modeling scales. The project is quite flexible and depending on emerging opportunities. You may focus also on modeling for induced seismicity forecasting (e.g. for real-time mitigation purposes) or machine-learning approaches.
The work will be conducted at SED under the supervision of Dr. Antonio Pio Rinaldi and Prof. Stefan Wiemer.
You are highly motivated candidate and have strong curiosity about numerical modeling of coupled fluid flow and geomechanics:
