The photo shows the seismological station OGCY located in Champagny-en-Vanoise (Savoie) at the end of the works. On the left you can see the ABAC cabinet and on the right you can see the nozzle head covering the instrument. The work, including the drilling, was carried out at an altitude of 2200m, on a site that is difficult to access, next to the Vanoise National Park, on the place called "Le Tougne". The drilling is 6m deep (Résif standard) and the team hit the healthy rock at 1.5m. Work began on 31 August 2020 and was completed on 11 September 2020. The station is integrated into the Permanent Broadband Network (RLBP) of the national research infrastructure Résif, dedicated to the observation and understanding of the Earth's internal structure and dynamics. Résif is based on high technology observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected enable the study, with high spatio-temporal resolution, of ground deformation, surface and deep structures, local and global seismicity and natural hazards, particularly seismic, on French territory. Résif is integrated into the European (EPOS - European Plate Observing System) and worldwide systems of instruments that allow us to image the interior of the Earth as a whole and to study numerous natural phenomena.
