The Computational Seismology Group in the Department of Earth Sciences at ETH Zurich is searching for an enthusiastic PhD student, to work on the inversion of ambient seismic noise for 3D Earth structure.
PhD Position for "Full Waveform Ambient Noise Tomography"
Project description: The ambient seismic noise field contains valuable information about 3D Earth structure that can be extracted by cross-correlating noise recorded at pairs of seismic stations (e.g. Shapiro et al., 2005). To avoid artifacts in such “noise tomographies”, the characteristics of the ambient noise field must be modelled accurately. The goal of this PhD project is to combine sophisticated models of ambient seismic noise (Stutzmann et al., 2012) and fully numerical 3D wave propagation techniques into an ambient seismic noise tomography on the global scale. This work will benefit from the high-performance computing and data processing capabilities of the Swiss National Supercomputing Center.
This four-year PhD will be in close collaboration with the Seismology Group at the Institute de Physique du Globe (IPG) in Paris; and regular visits to IPG will be strongly encouraged and supported. A solid background in geosciences, mathematical physics or numerical modelling is desirable but not required.
