Action 1.2: Numerical modelling of deformation in metropolitan France

We aim at developing models for France that include the main tectonic structures, and to test various processes that can control their deformation (Alpin collision, medio-atlantic ridge, erosion,…).


Ongoing and recently published works by Geosciences Montpellier Lab [Vernant et al., 2013 and Chéry et al., 2016] and based on numerical modeling put in light the importance of surface loading in the alpine current deformation. By using the ADELI code, the objective here is to analyze deformation location at the scale of the whole French metropolitan territory, according to different forcings and to compare results to observations (seismicity mainly, and GPS data when available).


This work is done in close collaboration with 2 ongoing PhD thesis at Geosciences Montpellier Lab on i) deformation rate observed through GPS (by C. Masson) and ii)theoretical models to take into account structural inheritance  in deformation numerical modeling (by A. Tarayoun). In addition erosion rates characterization in Pyrenees and Cévennes will be calculated  to add constraints to models.

Program of research

Work plan includes 3 main steps:

  1. 2D numerical models that take into account postglacial rebound;
  2. Add of structural inheritance in models (weakness zones);
  3. Implementation of tectonics velocities in models.
