PhD Position (2 of 3) in Earthquake Seismology and Hydromechanics
100%, Zurich, fixed-term
print Drucken
The Institute of Geophysics at the Department of Earth and Planetary Sciences of ETH Zurich has three open positions
for full-time (100%) PhD students in earthquake seismology and hydromechanics. This is the advertisement for PhD #2,
which focusses on the hydromechanics of complex fault zones.
Project background
The Bedretto Underground Laboratory for Geosciences and Geoenergies ("BedrettoLab") is a unique research facility of
ETH Zurich that allows studying earthquake physics, hydromechanics and deep geothermal energy under in-situ conditions.
In the context of a global flagship project in earthquake seismology - the Fault Activation and Earthquake Rupture
(FEAR) project - we are working to induce and study earthquakes with magnitudes of ~1.0 on a natural Alpine fault zone.
The BedrettoLab provides direct access to the target fault zone at a depth of ~1km, such that we can place monitoring
equipment directly on and around the fault zone. Because of this direct access, we can potentially observe, model and
understand earthquake dynamic and hydromechanic processes in exceptional detail.
The target fault zone has been extensively characterised with a wide range of geophysical and geological methods. The
detailed knowledge of in-situ fault zone properties allows us to study the intricate relations between these properties
and fault zone behaviour, in terms of seismicity, hydromechanics, and earthquake dynamics. In this context, we are
looking for three highly motivated candidates to embark on a PhD on the inter-connected topics of 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 the description for PhD #2. You will find an equivalent advertisement for the
other two positions on the same platform.
The 3 successful PhD candidates will join the Bedretto Team, a large, international team of scientists, who together
strive to advance our understanding of fault zone processes and earthquake physics. The PhD programs will focus on data
from the major upcoming experiments of the FEAR project, planned between November 2024 and December 2026.
Job description
The project of PhD #2 focusses on the hydromechanical phenomena that are key drivers for induced seismicity. While the
pressure field leading to induced earthquakes is often represented with simplified flow geometries, actual flow fields
in complex faults may be strongly heterogeneous and often channelized. The poroelastic field produced by these flow and
pressure patterns must be interpreted by considering their full complexity. Only then can induced seismicity patterns
(PhD#1) and rupture dynamics models (PhD#3) be embedded in a hydromechanical understanding of a complex fracture zone.
This PhD project will expand on the geological, and hydrological characterization of the target fault zone of FEAR to
understand the flow dimensionality as well as heterogeneity of the flow field based on tests at different pressure
levels and depths of investigation from the test boreholes. A conceptual heterogeneous hydrogeological model is built
and linked to poroelastic signals recorded on strain and pressure sensors as well as at special probes dedicated to
inferring 3D dislocation along the reactivated fracture system. Finally, conceptual models and observations will be
supported by numerical models that allow representing the full hydromechanical responses to fluid injections. The
hydromechanical understanding thus acquired is strongly linked to the induced seismicity characteristics inferred by
the PhD #1 in two ways; hydromechanical models help understanding induced seismicity patterns, while these patterns in
turn help building the heterogeneous hydromechanical models. Similarly, the hydromechanical models are also related to
the rupture dynamics models of PhD #3. Thus, the research of all three PhDs together not only improve our understanding
of earthquake physics and earthquake hazard, but also helps the safe development of geoenergy resources.
Profile
We are looking for an enthusiastic and ambitious young scientist with a knack for quantitative problem solving,
coding, and for working with large data sets. Additionally, technical skills and willingness to independently acquire
data from hydrological field tests is important. The position requires a Masters' degree in Earth Sciences, Physics,
Applied Mathematics, Engineering or a related discipline. You should have an interest in both field work as well as
data processing, analysis and modelling skills in common scientific languages such as Python or Matlab. Importantly,
working in an underground laboratory means working in a team. The position requires excellent teamwork abilities and
communication skills, including good spoken and written English skills. You will be expected to develop and implement
an independent research agenda, to publish papers in high-level peer reviewed journals, participate in international
conferences, and to perform basic teaching assistant duties.
