Welcome to the Gravitational Landslide Observatory by Geoazur

The Gravitational Landslide Observatory conducted by Geoazur aims at studying and understanding the processes related to the dynamics of lanslides - triggering, propagation, external forcings.

The analysis of the processes and the numerical modeling of their time-space variations become consistent by developing continuous multidisciplinary measurements on observation spots. The Geoazur Gravitational Landslide Observatory sets instrumentation both for earth and submarine landslides and ensures permanent monitoring. It makes available free online the raw databases and analysis results that are produced, so that they are disseminated to the scientific community and decision makers:

  • on earth, records of resistivity variations (electrical tomography), kinematics (tacheometry and GPS), mass movement (inclinometry), piezometric levels and rainfall;
  • in the sea, records of physical, chemical, biogeochemical and biological parameters, in submarine deposits or even in the shelf (well drilling), on the ocean floor, in the water column and in the atmosphere near the interface.

Multi-scale observations are carried out on sites that are typical of rock mass movement and gravitational slope deformation, in particular on the first landslide in Europe regarding the sliding volume (La Clapière, French Alps), the most active continental rift in Europe (the Gulf of Corinth, Greece), the passive continental margins of the western and eastern Mediterranean (Ligurian ; The Nile), the Andean active margin...
