High resolution imaging of the subduction interface using microseismicity

PhD position – seismicity of the subduction interface

Main host institution: Christian-­Albrechts University Kiel, Germany

Secondement Institution: REPSOL, Spain T

The Department of Geosciences at the University Kiel seeks to appoint a PhD student in “High resolution imaging of the subduction interface using microseismicity”. The successful applicant will join the seismology group at University Kiel and will work with Prof. T. Meier, Prof. W. Rabbel, Dr. C. Weidle (CAU Kiel), Prof. L. Boschi (UPMC), Prof. M. Scambelluri (University Genova), Dr. V. Sallares (CSIC Barcelona) and REPSOL.

Available data of previous and ongoing passive seismic experiments in the Hellenic subduction zone (EGELADOS, HADES) are to be used to locate microseismicity along the subduction interface with high accuracy. Cluster analysis and relative locations are to be applied in order to image active faulting and migration of seismicity. This will help to understand seismic coupling in the seismogenic zone as well as triggering mechanisms of intermediate depth seismicity like fluid migration beneath the volcanic arc. The results are to be compared to local earthquake tomography, receiver function studies and deep seismic sounding (ESR3, ESR5, REPSOL). Specific emphasis will be given to the comparison between a retreating, strongly segmented and weakly coupled subduction interface (Hellenic subduction zone) with  an advancing, strongly coupled one (Chile).

Candidates must hold an MSc in Geophysics, Earth Sciences, Applied Mathematics, Physics or a related discipline. Experience in seismology, wave propagation, location of earthquakes, signal processing, and programming languages is highly advantageous.

During the PhD, the candidate will strongly interact with the ZIP participants and will specifically collaborate with the secondment institution REPSOL.

CAU Kiel is committed to employing more handicapped individuals and to increasing the share of women in areas where they are underrepresented, and therefore expressly encourages applications from such qualified individuals.

Starting date is expected between March and May 2014. The position will be funded for 3 years. New deadline to apply: Feb 15th, 2014.
