Collaborating institutes

OMIV is a federation of several Earth Sciences Departments in France.

EOST-IPGS is coordinating the national observatory, is responsible of the Super-Sauze and La Valette landslides. It coordinates the acquisition and the analysis of the displacement/deformation observations.

OSUG-ISTerre is responsible of the Séchilienne and Mas d’Avignonet landslides and of the St-Eynard rockfall affected cliff. It coordinates the acquisition and analysis of the seismological observations, and conributes to the analysis of times series of point cloud datasets for defining evolution of the slope surfaces.

OCA-GeoSciences Azur is responsible of the La Clapière and Vence landslides. It coordinates the acquisition and analysis of the meteorological observations.

THETA-Chrono Environnement coordinates the acquisition and analyses of the hydro-geochemical data. It analyzes the water quality at La Clapière and Séchilienne landslides.

OREME-GM is responsible of the Pégairolles landslide. It coordinates the acquisition and analysis of the hydro-geophysical data.

IUEM-LGO is responsible of the Porsmillin rockfall affected cliff. It contributes to the analysis of times series of point cloud datasets.

LETG/Caen is responsible of the Villerville landslide and the Cap d'Ailly rockfall affected cliff.

EMMAH analyses the water quality at the Super-Sauze landslide.

CEREMA (Sourdun, Bron, Nice) contributes to the knowledge at the Séchilienne and La Clapière landslide and share expertises on point cloud datasets analyses and numerical geotechnical modelling.

ONF-RTM (Departments 38, 04, 05 and 06) contributes to the knowledge at the La Valette landslide and share expertise on risk assessment procedures.

The data collection on the landslides are operated partly as a task of the OMIV Observatory, and partly through research projects of the partners. The situation of data collection is thus diverse per study site, and some data acquired through research projects may be discontinuous or not distributed through the website.
The distributed OMIV data are quality-controlled. Some interruptions of data records may happen because of sensor or telemetry dysfunctionning. Inaccuracies in the sensor data (because of instrument malfunctions or physical changes at the measurement site) have been corrected or are indicated in the datasheets. Higher resolution or more complete datasets may be available at some sites and may be acquired by contacting the scientists in charge.
Data users are cautioned to consider carefully the nature of the information before using it for science or for operational decisions that concern personal or public safety.
