Abstract
This photo was taken as part of a 2008 remeasurement of some of the sites in the ResPyr network established in 1995. The aim of this campaign is to quantify the current deformation rates in the Pyrenees. The photo shows the Trimble Geodetic Zephyr antenna, which belongs to the National Mobile GNSS Park (GPSMob), a specific action 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 throughout France. The data collected allows 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.
