Lithosphere tectonics and mechanics


General Presentation

Trench on the Himalayan frontal thrust

The primary objective of the Tectonics team of the IPGP is be to pursue fundamental research to push frontiers of our knowledge on the mechanics of the lithosphere, and on interaction of deep-seated tectonic processes with surface processes. We study and model strain in the lithosphere in a broad range of time scales, from transient deformations associated with the earthquake cycle to the long-term processes that build-up permanent deformation and shape the landscape. We intend to bring a strong original method, based on original observations made in a large range of time- and space-scales, using multidisciplinary approaches applied to selected ‘first-class’ examples, which are chosen for their high potential to tackle first-order problems in actively deforming regions. This method allows us to bridge the gap between short-term and long-term processes, to test physical parameters and laws on rapidly evolving tectonic systems, and to address problems  of natural hazard assessment.


The Carribean subduction
Two main research themes, with participation of most team members to both themes, cover a large part of our research topics and projects:


1) Geometry, propagation, dynamics of faulting, from observations to fracture mechanics modeling


2) Plate coupling on subduction margins, from the seismic cycle to mountain building and landscape evolution
