Geophysics of seismic and landslide risks
The Geophysics of seismic and landslide risks team focuses mainly on two types of risks, gravity and seismics, and on coupling between the subsoil (from the surface to a few kilometres) and environmental demands.
The team has four main objectives:
- disaster prediction, which involves identifying early warning signals when there are no early warning signs, predicting disaster scenarios and their effects.
- understanding the physical mechanisms leading to these disasters (rupture, ground movements, structural damage).
- understanding the coupling between the environment and solid earth.
Several approaches are used: long-term observation (permanent geophysical networks), semi-permanent or temporary observations, subsoil surveys, numerical simulation, laboratory experiments.
Most of the team’s work is instrumental and is based on measurements and observations made in the field and in the laboratory.
Our work is carried out in various frameworks, with coordination or partnership in ANR, European, R&D with industry projects, and collaborations with countries in the South via IRD and/or MAE and UNDP.
