100%, Zurich, fixed-term
The Institute of Geophysics at the Department of Earth and Planetary Sciences of ETH Zurich is pleased to announce three open positions for full-time (100%) PhD students specializing in earthquake seismology and hydromechanics. This position focuses on the seismicity of complex fault zones.
The Bedretto Underground Laboratory for Geosciences and Geoenergies ("BedrettoLab") is a distinguished research facility at ETH Zurich, enabling the study of earthquake physics, hydromechanics, and deep geothermal energy under in-situ conditions. Our work is part of the global flagship project in earthquake seismology—the Fault Activation and Earthquake Rupture (FEAR) project—which aims to induce and study earthquakes with magnitudes of approximately 1.0 on a natural Alpine fault zone. The BedrettoLab offers direct access to the target fault zone at a depth of about 1 km, allowing us to place monitoring equipment on and near the fault zone. This unique access enables us to observe, model, and understand earthquake dynamics and hydromechanics in remarkable detail.
The target fault zone has been extensively characterized through various geophysical and geological methods. Our comprehensive understanding of in-situ fault zone properties allows us to explore the intricate relationships between these properties and fault zone behavior in terms of seismicity, hydromechanics, and earthquake dynamics. We are searching for three highly motivated candidates to undertake PhD projects on interconnected topics: i) Seismicity of a complex fault zone (PhD #1); ii) Hydromechanics of a complex fault zone (PhD #2); and iii) Rupture dynamics of a complex fault zone (PhD #3). This is an overview for PhD #1, while equivalent advertisements for the other two positions will be found on the same platform.
The three successful PhD candidates will join the Bedretto Team, a large, international group of scientists dedicated to advancing our understanding of fault zone processes and earthquake physics. The PhD programs will focus on data from significant upcoming experiments of the FEAR project, planned between November 2024 and December 2026.
This PhD project (#1) centers around the relationship between seismicity and fault network architecture. The fault zone targeted by the FEAR project is exceptionally well-constrained, utilizing diverse datasets such as active seismic campaigns, borehole analyses, and highly sensitive seismicity catalogs. This extensive data coverage presents a unique opportunity to examine how seismicity reflects fault zone properties and, conversely, how these properties influence seismicity patterns.
The successful candidate will explore these questions using exceptional datasets from the forthcoming FEAR experiments. The candidate is expected to enhance existing fault network reconstruction algorithms utilizing both supervised and unsupervised deep learning methods. These algorithms will process seismicity alongside complementary input data (e.g., strain, borehole, and geological observations) to create a detailed 3D discrete fracture network model of the target fault zone. This model will aid in studying the impact of fault network properties on seismicity and earthquake source characteristics. Collaboration will be essential, especially with PhD #2 to investigate the connection between seismicity and fault zone hydromechanics, and with PhD #3 to explore the relationship between seismicity and rupture dynamics of larger events. The research conducted by all three PhD candidates may significantly enhance our understanding of earthquake physics, earthquake hazard, and the safe generation of deep geothermal energy.
We are seeking an enthusiastic and ambitious early-career scientist with a knack for quantitative problem solving and coding, particularly in working with large datasets. Candidates must possess a Master's degree in Earth Sciences, Physics, Applied Mathematics, Engineering, or a related discipline. A strong interest in developing exceptional data processing, analysis, and modeling skills using common scientific languages such as Python or Matlab is required. Additionally, successful candidates should demonstrate excellent teamwork capabilities and communication skills, with proficiency in spoken and written English. The role entails developing an independent research agenda, publishing in high-level peer-reviewed journals, participating in international conferences, and performing basic teaching assistant duties.
This project exists within a vibrant research environment, characterized by a large, diverse, and interdisciplinary research team. ETH Zurich boasts one of the premier Earth Science and Geophysics programs worldwide, complemented by outstanding resources for mentoring and infrastructure. The city of Zurich is renowned for its high standard of living and is conveniently situated near the Swiss Alps and the heart of Western Europe.
