Solar panels on an observation site belonging to the Observatoire Multidisciplinaire des Instabilités de Versants (SNO-OMIV) in Séchilienne (Isère)

Abstract

L'Observatoire Multidisciplinaire des instabilités de versants a pour mission de surveiller l'évolution à long terme des mécanismes de contrôle des glissements de terrains. Il collecte et interprète des observations multi-sources de plusieurs versants instables. Il est également chargé de la coordination de la tâche d'observation géodésie et de la responsabilité nationale du service. L'observatoire OMIV a focalisé ses mesures sur quatre sites représentatifs des mécanismes observés dans les Alpes françaises (roches tendres/dures, mouvements lents ou plus rapides) dont celui du glissement de Séchilienne, où l'on peut voir les panneaux solaires installés sur un site d'observation. Un système de surveillance est mis en place par le CEREMA Rhône ALPES depuis 1986, progressivement développé et automatisé au fil des années. Il comprend des capteurs pluviométriques et nivométriques, 27 bases extensométriques (ouverture de grandes fractures), des mesures géodésiques par laser (41 repères) depuis le versant opposé et depuis 2000, des mesures de contrôle GPS et radar. Ce site d'observation est intégré à Résif, une infrastructure de recherche nationale dédiée à l’observation et la compréhension de la structure et de la dynamique Terre interne. Résif se base sur des réseaux d’observation de haut niveau technologique, composés d’instruments sismologiques, géodésiques et gravimétriques déployés de manière dense sur tout le territoire français. Ces données permettent d’étudier avec une haute résolution spatio-temporelle la déformation du sol, les structures superficielles et profondes, la sismicité à l’échelle locale et globale et les aléas naturels, et plus particulièrement sismiques, sur le territoire français. Résif s’intègre aux dispositifs européens (EPOS - European Plate Observing System) et mondiaux d’instruments permettant d’imager l’intérieur de la Terre dans sa globalité et d’étudier de nombreux phénomènes naturels.

The mission of the Multidisciplinary Observatory of Slope Instabilities is to monitor the long-term evolution of landslide control mechanisms. It collects and interprets multi-source observations of several unstable slopes. It is also responsible for the coordination of the geodetic observation task and the national responsibility of the service. The OMIV observatory has focused its measurements on four sites representative of the mechanisms observed in the French Alps (soft/hard rocks, slow or faster movements), including the Séchilienne landslide, where the solar panels installed on an observation site can be seen. A monitoring system has been set up by CEREMA Rhône ALPES since 1986, progressively developed and automated over the years. It includes rain and snow sensors, 27 extensometric bases (opening of large fractures), geodetic measurements by laser (41 markers) from the opposite slope and, since 2000, GPS and radar control measurements. This observation site is part of Résif, a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodesic and gravimetric instruments deployed densely over the whole of France. These data allow the study of ground deformation, surface and deep structures, local and global seismicity and natural hazards, particularly seismic hazards, on the French territory with a high spatial and temporal resolution. Résif is part of the European (EPOS - European Plate Observing System) and global systems of instruments for imaging the Earth's interior in its entirety and for studying numerous natural phenomena.
