The EARTHQUAKE Team combines skills and expertise in all leading-edge fields relating to seismic hazard. It is composed of geodesists, tectonicists for active processes, hydromechanics, and seismologists for seismic source and strong ground motion.

Notre objectif ?
WHAT?
 Comprendre les séismes - initiation, propagation, occurrence dans le temps…
Understanding earthquakes - initiation, propagation, occurrence in time....

Pourquoi ?
WHY?

Pour mieux les anticiper et pourquoi pas un jour les prédire
For a better anticipation, and, why not one day, prediction of earthquakes

Comment ?
HOW?

En analysant les données de différentes natures : terrestres, marines et satellitaires
En créant des expériences pour les reproduire
En modélisant et simulant les processus
By analysing different kinds of data: terrestrial, marine and satellite
By creating experiments to reproduce them
By modelling and simulating processes

Trois questions scientifiques centrales - Three key scientific questions :

  1. Comment se répartissent et évoluent les ruptures sismiques et les glissements asismiques sur un système de failles ?
    How are seismic ruptures and asismic slips distributed and evolving over a fault system?
  2. Quel est le rôle des forçages (i.e. action des fluides, glissements asismiques, ...) dans la génération des séismes ?
    What is the role of forcing (i.e. fluid action, asismic slip,...) in the triggering of earthquakes?
  3. Comment accroître la précision des estimations d'aléa sismique ?
    How to increase the accuracy of seismic hazards?
