Offer DescriptionMissions In the context of a project funded by the Grand Prix Scientifique 2023 from the Simone & Cino Del Duca Foundation of the Institut de France, entitled: “Deep slab motions over the seismic cycle of great earthquakes from satellite gravity”, we are looking for a post-doctoral researcher in order to work on the geophysical modelling of slab deformations during the seismic cycle of great subduction earthquakes, constrained by satellite gravity data from the GRACE mission. This modelling work will complements the GRACE satellite gravity data analyses carried out by our team to extract gravity signals associated with great earthquakes. For that aim, the post-doctoral researcher will apply the numerical modelling code SPECFEM-X, in the context of a collaboration with the Queen's University (Canada) and with Geosciences Environnement Toulouse. He/she will seek to jointly model the gravimetric and crustal displacement signals associated with the pre-seismic phases of the 11 March 2011 Tohoku earthquake (Mw 9.0, Japan) and the 27 February 2010, Maule (Mw 8.8, Chile) earthquake, and possibly also their co- and post-seismic phases.
Activities
RequirementsValidate the use of the SPECFEM-X code by comparing its numerical predictions with results obtained in the case of dislocation models in a radially stratified Earth. Carry out a sensitivity study of the modelled signals to the lateral structure of subduction zones Model the GRACE gravimetric signals associated with the pre-seismic phases of the 11 March 2011 Tohoku earthquake (Mw 9.0, Japan) and the 27 February 2010, Maule (Mw 8.8, Chile) earthquakes, and jointly explain the small amplitude of any related crustal displacement signal. Possibly extend the modelling to the co- and post-seismic phases of these events

Additional comments
The institut de physique du globe de Paris 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 Team Geodesy comprises about 16 permanent staff and is located in the Lamarck building of IPGP (Paris 13th district). Our research work aims at improving the determination of geodetic reference quantities (terrestrial reference frame and surface velocity and displacement fields, geoid and gravity field), while better understanding the geodynamical and climatic processes affecting these observables through the deformations and mass redistributions they generate. For that, we develop innovative methodologies of analysis of the observations, combined with their geophysical modelling, and carry out various applications of geodesy to the study of the Earth's system, from the shallower fluid layers to the deeper internal ones. Finally, we actively support and participate to the development of innovative instrumentation and observation concepts in geodesy and gravimetry, both on ground and on-board satellites.
