Winter installation of the Trillium 120PH1 sensor in the ENAUX site at Villeneuve d'Entraunes (Alpes-Maritimes)


Description : The photo shows the tripod used with a winch in order to process the descent of the sensor and a special device created by Geoazur to maintain the geographical direction. This observation site is part of the French seismological and geodetic network 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, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is part of the European (EPOS - European plate observing system) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.
