Post-doctoral position in image correlation applied to earthquake geology M/F

Job Description

Missions

The post-doctoral position is opened in the framework of the Be_Fact ERC project led by Y. Klinger. The target of this project is to elucidate the relation between fault geometry and earthquake rupture for large continental earthquakes: How does the geometry of a fault system evolve through successive earthquake cycles and in parallel, how such fault geometry controls the start and stop of an earthquake rupture ?

Activity

The project for the post-doctoral position is to work on the correlation of old aerial photograph in order to measure ground deformation associated with past earthquakes and determine information about earthquake source processes. The general framework to conduct this type of correlation has already been partly developed at IPGP where the group has a large experience with the MicMac free software package that is used for correlation. However, working with old aerial images require specific processing to be able to account for difficulties due to film distortion, difficulties to determine homologous points etc... Hence, in addition to processing of images, the post-doctoral fellow will likely have to involve on small methodological development to adapt the tools to specific cases.
The primary target will be the processing of the images acquired before and after the Mw 7.6 1976 Guatemala earthquake, which source parameters remain poorly known so far. Using the ground deformation resulting from image correlation, the second step of the project will be to work on the earthquake source process of this event that ranks among the largest continental earthquake so far.
The post-doctoral fellow will be in charge of processing the data and analyzing the results. Eventually, the post-doctoral fellow is expected to publish results in international scientific journals and to present in international meetings.
The work will be conducted in collaboration with Lulin Zhang, research engineer at IPGP with a strong expertise in photogrammetry. Interactions are also expected with other team members, and more specifically with Arthur Delorme, engineer, and Perrine Salvan, PhD student, both strongly involved in image correlation.

Your Work Environment

A world-renowned geosciences organisation, the IPGP is associated with the CNRS and an integrated institute of the Université Paris Cité. Bringing together more than 500 people, the IPGP studies the Earth and the planets from the core to the most superficial fluid envelopes, through observation, experimentation and modelling.
The research aeras are structured through 4 main unifying themes: Interiors of the Earth and Planets, Natural Hazards, Earth System and Origins.
The IPGP is in charge of labelled observation services in volcanology, seismology, magnetism, gravimetry and erosion. And the IPGP's permanent observatories monitor the four active French overseas volcanoes in Guadeloupe, Martinique, Réunion Island and Mayotte.
The IPGP hosts powerful computing resources and state-of-the-art experimental and analytical facilities and benefits from first-class technical support. The IPGP provides its students with geosciences training that combine observation, quantitative analysis and modelling, and that reflects the quality, richness and thematic diversity of the research conducted by the IPGP teams.

Team Department :
The position will be in the group of Tectonics and Mechanics of the Lithosphere at IPGP. The tectonics team in IPGP include 11 faculties, 3 staffs (scientific and administration) and about 15 students (PhD and post-doctoral fellows). This group is focused on the deformation of the Lithosphere at all scales of space and time, from long term to instantaneous deformation. Approaches used by the team include paleoseismology, structural geology, sedimentology, remote-sensing and geodesy, and numerical modeling.
